max speed of cart...
A persone rides in a cart moving at a speed v at the top of a hill that is in the shape of an arc of a circle with radius r.
determine the maximum speed that the cart may travel at the top of the hill without losing contact with the surface.
How do i know that the cart...
here's a tough one :S
A 70kg person rides in a 30kg cart moving at 12 m/s at the top of the hill that is the shape of an arc of a circle with radius of 40m.
a) What is the apparent weight of the person as the cart passes over the top of the hill?
b) Determine the maximum speed that the...
Me and my buddy had a discussion the other day.
Imagine the scenario with the donkey that has a danglin carrot in front of him. If we swap the donkey for a cart and the carrot for a magnet, what would happen?
My buddy was pretty sure that the cart would move, and I thought that it wouldn't...
I'm having trouble getting started on this entire problem. I've re-drawn it, I'm given the mass of the cart, and the radius of the loop.. but I have absolutely no idea how I can calculate even the first part of this (minimum high h).
I'd greatly appreciate any help anyone could offer. Thank...
This is my first physics class and I'm looking to do more than just pass it, I want to understand everything fully. Anyway, my class just started going over Newtons first, second and third laws, and I'm having trouble with a problem in my book (this problem...
Jill has just gotten out of her car in the grocery store parking lot. The parking lot is on a hill and is tilted 3 degrees. Fifty meters downhill from Jill, a little old lady let's go of a fully loaded shopping cart. The cart, with frictionless wheels, starts to roll straight downhill. Jill...
Hi,
I am wondering if one cart is rolling down a ramp and there is another cart at the bottom. What wil happen to the bottom cart as far as energy goes(law of conservation of energy)? If I had the car at the top's velocity, displacement, etc how would I go about calculating how the far the...
Question: Suppose you have measured the time (delta T) required for a glider to travel several distances (delta X) down an inclined plane. After plotting the data points on a graph of delta X vs. (delta T)^2, you find the slope of the best fitting straight line is 15cm/s^2. What is the...
I'm trying to build a low profile rolling flat cart. I am running into issues with calculating the material thickness needed to prevent warping, as well as total failure.
The consisits of a 4 foot x 8 foot sheet of plywood of tbd thickness. On the bottom of the cart will be 12 tandem wheel 2"...
I'm building a cart which must be powered by TWO elastic bands only,
it must ran at least 2 meters, which isn't hard, but my goal is at
least 12 meters, which isn't very hard either(the longer the better).
I have some ideas of how to power the cart and please help me to
choose...
I'm having trouble with this if anyone can help thanks.
A cart with a mass of 2kg is pulled across a level desk by a horizontal force of 4N. If the coefficient of kinetic friction is 0.12, what is the acceleration of the cart?
Hi I have this problem involving a cart which is losing sand
It says:
A cart with initial mass M and a load of sand \frac{1}{2}M loses sand at the rate k kg/s. The cart is pulled horizontally by a force F. Find the differential equation for the rate of change of the carts velocity in terms...
Three Physics 111 AP students, each having a mass of 60kg, climb onto a large flatbed cart that has a mass of 120 kg. Standing at one end and taking turns they run to the opposite end and jump off, one immediately following the other, each with a velocity of 10 m/s with respect to the cart...
A 1000 kg cart is rolling to the right at 1.70m/s . A 70.0 kg man is standing on the right end of the cart.What is the speed of the cart if the man suddenly starts running to the left with a speed of 7.00 m/s relative to the cart?
really boggles my mind, should i be using
=(m1 +m2)Vf -...
OK this problem is probably really easy, but I totally have no idea how to handle it. Please help! Here goes:
A 20kg cart on wheels has been pushed up against a wall with a spring (k= 244N/m) between the cart and the wall. If the spring is compressed a distance of 0.1m and a force of 20N is...
Force Question - Still want another oppinion!
A man pulls a cart on a friction fee surface by means of a pulley and rope. He pulls the rope at 600 N. Now replace the man's action with an iron weight of 60 kg so that it is attached to the end of the rope. The cart is again set in motion. Is...
Hello, I've just joined this forum in hopes of finding some help to my physics problems. I usually can find out what to do by myself, but this problem seems to be requiring some advanced concepts...or it maybe is so that I'm just not using my noodle.
A car is sliding down an inclined plane...
I've been having troubles figuring out this question, because the cart is not actually attached to either spring nor always touching one. Any help would be appreciated.
A cart moves without friction between two springs, back and forth. Both springs have a spring contact of D = 72 N/m. At...
ok I have another problem here. Please help me. Thank you in advance.
A 1.50 kg sled scrapes down a grassy incline where the coefficient of friction is 0.678. The sled moves at a constant speed f 4.50 m/s and it takes 12.5 seconds to travel the entire length of the hill to the bottom...
