A 15 kg box, initially at rest, slides down a frictionless ramp 10 m high. (a) Compute the velocity of the box as it reach the bottom of the ramp. (b) If it continuously slide horizontally in a horizontal plane with a coefficient of friction μ,-0.15, how far from the bottom of the ramp would it slide before coming into a complete stop? 1.

A car (initially at rest) slides down a smooth, 30 m long ramp (neglect friction on the ramp) that is inclined at 6 deg. from the horizontal. At the bottom of the ramp, this car hits a second, identical car that is also initially at rest on a horizontal road. The effective coefficient of friction for the cars on the road is 0.6. How far will the cars roll after the crash before stopping?

A 700 kg car is coasting along a level road, slowing down at an acceleration of 7.11 m/s^2 until coming to a stop. What is the minimum coefficient of friction between tires and roadway if this is to be possible? Assume the wheels are not locked, in which case we are dealing with static friction -- there's no sliding.

As shown below (not to scale), a block of mass starts from rest
and slides down a frictionless ramp of height h. Upon reaching the
bottom of the ramp, it continues to slide across a flat
frictionless surface. It then crosses a "rough patch" on the
surface of length d=10m. This rough patch has a coefficient of
kinetic friction uK=.1. After crossing the rough patch, the block's
final speed is vf=2m/s. What is the height of the ramp? Hint: I...

45 kg is released from rest from the top of a rough ramp, with Mass - coefficient of kinetic friction 0.25 between the block and the incline, of height 3.2 m and length d 5.5 m. At the bottom of the ramp, the mass slides on a horizontal, frictionless surface until it compresses a spring of spring constant k 2. 110 N/m. a. Calculate the speed of the mass at the bottom of the ramp? b. How far does...

3) Referring to the picture below, consider a block of mass m-1kg, sliding down a ramp with that is frictionless. The block continues to slide a distance d along the table, which has coefficient of friction u 0.2. Using conservation of energy answer the following: a If the block starts at a height h=5.1m how fast is it going at the very bottom of the ramp? b. The block comes to a stop a distance, d, from the bottom of...

A cart starts at rest and rolls down a ramp as shown below. Gravity causes the cart to have a constant acceleration as it travels along the ramp. When it reaches the bottom of the ramp, friction with the flat surface causes it to gradually slow to a stop Draw graphs of the acceleration, velocity, and position of the cart throughout its motion as a function of time. The graphs should be laid out as they were on the computer...

A 5 Kg box initially at rest slides down a ramp with friction acting on the box. At the top of the ramp the box has a potential energy of 120 J. At the bottom, its kinetic energy is 30 J and the work done by the friction has a magnitude of 20 J. What is the mechanical energy of the box at the bottom of the ramp?

4. Energy and Momentum for 15 points: A 200 gram lab cart is initially at rest on top of a 50 cm ramp, as shown. Note that the wheels are very light and the axle has no friction in it. You push the cart as it moves through a distance of 20 cm with a constant force of 10N in a direction oriented 20 degrees below horizontal. After you stop pushing on the cart, it encounters a ramp, and rolls...
