    What angle should movers set their truck ramp to minimize work?

    Movers want to set the ramp of their truck so that the work they do against the combination of gravity and friction is a minimum for crates moving up the ramp with constant velocity. µ is the coefficient of kinetic friction and θ is the angle between the ramp and the ground. For the work to be a...

    How Far Does a Block Travel Up an Incline Before Stopping?

    Inclided plane Hi! I have a physics question. A block with mass m=14.7 kg slides down an inclined plane of slope angle 44.4* with a constant velocity. It is then projected up the same plane with an initial speed 2.55 m/s. How far up the incline will the block move before coming to rest...

    Conservation of Energy on Inclined Plane

    Hi, I am confused about something. I understand how one gets the equation 1/2kx^2=mgh, and so if 1/2kx^2=0, then mgh=0, but this doesn't make sense to me. Isn't it true the energy is converted, so it's impossible to have both equal zero? One could equal zero, and the other would be at a...

    Kinetic Friction on inclined plane problem

    Been trying to comprehend this one for a few hours: The coefficient of kinetic friction between a block and an inclined plane is 0.20 and the angle is 60 degrees. What is magnitude of a? The book says 7.5 m / s^2 How do I figure this with no speeds or distances or even a mass?

    Frictionless inclined plane problem

    Hi, I am trying to finish my homework and I can't figure out one problem. Can you help me, please? A block (mass m1) lying on a frictionless inclined plane is connected to a mass m2 by a massless cord passing over a pulley. a) Determine a formula for acceleration of the system of the...

    Block on an accelerating inclined plane

    I have a problem (it was homework, but I already turned in my wrong answer) dealing with a block stationary on an accelerating inclined plane. There is a force applied horizontally to the inclined plane, which has an angle of 35 degrees above the horizontal. A box of mass 0.5 kg is on the...

    Normal forces on inclined plane

    A 1.0 kg box on a 30 degree frictionless incline is connected to a 3.0 kg box on a horizontal frictionless surface. The pulley is frictionless and massless. I got n=mg for m1 in the y direction, and in the x direction i got F+T=m1a. For m2 in the y direction i get N-m2gcos(theta)=0, and in...

    Particle Resting On An Accelerating Inclined Plane Problem

    I am having difficulties finding an acceptable rationale for my solution to Problem 41 of Chapter 5 from Physics for Scientists and Engineers, 4th edition, by Paul A. Tipler: Lou has set up a kiddie ride at the Winter Ice Fair. He builds a right-angle triangular wedge, which he intends to...

    Object sliding down inclined plane

    An object slides down an inclined plane of angle 30 degrees and of incline length 4m. If the initial speed of the object is 5m/s directed down the incline, what is the speed at the bottom? Neglect friction. I used Kinitial+Uinitial=Kfinal+Ufinal. I got 2gh+5^2=v^2, but when I solve for v...

    Physics: Box sliding down an inclined plane

    i'm trying to learn this stuff on my own so please bear with me. here's the problem: you have two mass, a 10kg on a frictionless 35 degree inclined plane, which is attached to 20kg mass via a pulley cord to hang vertically. Whats the aceleration? Solution: for the box hanging freely...

    Force and Friction on an Inclined Plane

    This question is driving me insane please help. A 25 kg block of ice slides down an incline 2.5 m long and 1.5 m high. A man pushes up the ice parallel to the incline so it slides down at a constant speed. The coefficient of friction between the ice and incline is 0.10. Find the force...

    Gravity with Galileo's inclined plane?

    Hey everyone, I'm new here, so I'll let you know a little about me. I'm going to uconn right now, and my major is mechanical engineering. I have a question about a lab we did for my engineering class. We replicated Galileo's experiment with inclined planes, and our teacher told us to find...

    Cylinder on a frictionless inclined plane

    I just have a question about cylinder. If a cylinder is on a frictionless inclined plane, does it spin as it comes down? I guess on a level surface, frictional force is required for a cylinder to roll, but I'm not sure about inclined plane.

    How Do You Calculate the Coefficient of Kinetic Friction on an Inclined Plane?

    I need help with a problem. In the book, the mass, the elevation of the inclined plane, and the acceleration are given. I am told to find the kinetic Friction coefficient. What equation(s) would I use to solve this problem?

    What is the acceleration of a box on a 20 degree inclined plane?

    a box on a smooth inclined plane with an angle of 20 degrees to the horrizontal. If the inclined plane is 5 m long, how long does it take for the mass to reach the bottom of the inclined plane after the mass is released? I did sin 20 degrees x 5.0 m = 1.71 m how do i get the mass from this...
