Homework Statement Hey, I am not sure why I can't get the right answer for my online physics homework, it keeps telling me the answer I am putting is wrong! My question is: The light turns green, and a bicyclist starts forward with an acceleration of 1.0 m/s^2. How far must she travel to...

Homework Statement Sam, whose mass is 67 kg, takes off across level snow on his jet-powered skis. The skis have a thrust of 230 N and a coefficient of kinetic friction on snow of 0.13. Unfortunately, the skis run out of fuel after only 12. Homework Equations F-Fk=mA (Vx)f = (Vx)i +...

Homework Statement If something is moving at a constant acceleration (starting from 0 velocity) for a known period of time, how do you figure how far they've traveled? Eg. a car is accelerating at 2 m/s^2 for 20 seconds. I'm taking an algebra based physics course. Homework Equations...

Homework Statement Horizontal distance traveled by a projectile fired from the ground can be modeled by d= (v^2sin2x)/g, where v is initial velocity, x is the angle in degrees, and g is acceleration due to gravity. (This model neglects air resistance and assumes a flat surface) a) A...

Homework Statement A smooth plane is inclined at 73.74 Degrees to the horizontal a block of mass 5kg is on the slope. its 73.47 degrees inclined 5kg mass g = 9.8 Find the distance traveled by the block in 0.8 Seconds The Attempt at a Solution i can't quite remember how i find...

A Runner Completed four laps of a 400m track in 6.0 minutes. Find the distance traveled and displacement of the runner. Ok i know that distance would be 400m * 4 laps obviously but how would you write that out? What would a formula be? (Complete guess below, obviously not right.) d1 = 400m...

Homework Statement a box given an initial speed of 3.0 m/s up a 19.0° inclined track. The mass of the box is 20 kg, and the coefficient of kinetic friction between sled and incline is 0.20. How far up the incline does the box move? Homework Equations F=ma, n=63.8N, mukN=12.76 The Attempt at...

The speed of light is 3.00 x 108 m/s. How many miles will light travel in 19.8 µs? (One mile is 1.61 km.) I don't even know where to start, any help would be appreciated.

[SOLVED] Finding distance traveled of a dropped object Homework Statement Imagine that someone dropped a firecracker off the roof of a building and heard it explode exactly 10 s later. Ignoring air friction, taking g = 9.81 m/s2 and using 330 m/s as the speed of sound, calculate how far the...

A ball is pictched at a batter, the batter hits the ball at a 45 degree angle It just clears the outfield fence 98m away Find velocity of the ball when it left the bat. Assume fence is the same height as the pitch. Disreguarding air friction I can't figure out how to find initial velocity.

Homework Statement A 50g ice cube can slide without friction up and down a 30 degree slope, compressing the spring 10cm. The spring constant is 25N/m. When the ice cube is released, what distance will it travel up the slope before reversing direction. Homework Equations I am not sure...

Do you know if these two formulas are the same? Avg. Velocity = Distance Traveled / Time Traveled & Avg. Velocity = V1 + V2 / 2 (V1 = d1/t1 & V2 = d2/t2) I have a problem that says that a plain goes from a place to another(1) and from there it goes to another place (2). So: t1 = 3 h...

Distance traveled by an accelerating truck with a steel load. With a twist! Homework Statement Consider a large truck carrying a heavy load such as steel beams. A significant hazard for the driver is that the load may slide forward crushing the cab, if the truck stops suddenly in an...

Homework Statement A dockworker applies a constant horizontal force of 74.0 N to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts from rest and moves a distance 13.0 m in a time 4.50 s. If the worker stops pushing at the end of 4.50 s, how...

CIRCULAR MOTION! Homework Statement A wheel 1 meter in diameter is rotating at 100 revolutions per minute along a level stretch. How far down the road does the wheel travel in hour? Homework Equations i think... The Attempt at a Solution 100 revs=200(pi) radians/60sec * 3600sec=...

HELP! question about total distance traveled for an object on a hill if you can help me in anyway, that'd be great! here's all the information. Buffy and Willow are playing miniature golf. Buffy putts her ball win an initial velociy of 2.0 m/s up a gradual incline in the direction of...

Hey guys! I have a question on a second problem as well... While chasing Mitch for destroying his car, Batman does the following in Skid's stolen Pinto: 1. He starts from rest and accelerates at 0.6 m/s^2 for 15 s 2. Travels at a constant velocity for 2 minutes 3. Slows to a stop...

I have this equation here and I don't see how I can isolate v, the speed of the ship... \frac{{2(4ly)(9.5x10^{15} \frac{m}{{ly}}}}{v} = \frac{{16y}}{{\sqrt {1 - \frac{{v^2 }}{{c^2 }}} }} y = years ly = light years The book doesn't tell you how it got v=0.447c, it just jumped to the...

Simple Harmonic Motion-Finding the distance traveled by the vibrating object? Hi, I would really like to know if my solution to the following question is correct, I would really really really appreciate it. A hanging spring stretches by 35cm when an object of mass 450g is hung on it at rest...

Ok so i found the angular accleration when the block of the mass is attached to the cylinder to be 70.03 when the mass weighs .47 kg. But i am having trouble finding the distance it has traveled from 0.51 s to .71 s assuming that at 0s the motion has begun. Does anyone have any ideas?

Hi -- I know this is so easy but right now I am a box of rocks. I think I am doing too much calculus and physics problems and just can not think of the simple things. What I am trying to do is solve this problem. Problem: A crate with mass 34.0 initially at rest on a warehouse...

A car starts from rest and accelerates uniformly for 8 s. The distance traveled in the 8 s is greater than the distance traveled in the first second by a factor of: ---- I think you use this formula, but I don't know. Vo = 0 X1 = 1/2at1^2 X2 = 1/2at2^2 X1/X2 = (1/2)at1^2 /...

An object moving along a curve in the xy-plane has position (x(t), y(t)) at time t with dx/dt = cos(t^3) and dy/dt 3sin(t^2) for 0<= t<= 3. At time t=2, the object is at position (4,5). a. Write an equation for the line tangent to the curve at (4,5). b. Find the speed of the object at time...

Once again, I've become stuck on the easiest problem in the chapter (though I'm steamrolling the tougher ones). I just can't get the concept of this one down I guess. Thanks for any help. A 4 Hz wave with amplitude 12 cm and a wavelength 30.0 cm travels along a stretched string. (a) how...

Hello, I have a small question. I just don't know where to go with it. If anyone could tell me where to start at that would be awesome. Please and thank-you. An automobile is braked to a stop with a uniform deceleration in a time of ts. Show that the distance traveled during this time is...
