7) A box of mass m slides down a ramp, starting at the top. The ramp has a base of length B and height of H. There is friction between the box and the surface of the ramp. The coefficient of frictions are pk and Hs. What is the velocity of the box when it reaches the end of the ramp? Can you use conservation of energy to solve this problem, why or why not? What...

6) A small ball of mass m sit atop a large hemisphere (a dome) of radius R. The ball begins to roll down the hemisphere. The location of the ball on the hemisphere makes an angle with the vertical. What is when the ball rolls off the hemisphere (the ball can not ride the surface of the hemisphere all the way down). 7) A box of mass m slides down a ramp, starting at the top....

oblem 2: A 5-kg box slides down a ramp. The ramp is l m in length and inclined at an angle of 30° as shown. The box starts from rest at the top. The surface friction coefficient is 0.25 1. Use energy methods to determine the speed of the box at the bottom of the ramp 2. How far does the box slide before stopping on the horizontal floor if it continues to experience the same friction coefficient. 1.00 m...

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...

3. Starting from rest, a box of mass M slides through a distance d down a incline. The coefficient of friction on the plane is ple (a) Draw a free body diagram. (b) Determine the work done by the gravity- express this in terms of M, g, e, d. (c) Determine the work done by the friction-express this in terms of M, g, 0, d, u. (d) Use Work-Energy theorem to determine the final velocity of the box.

A 600 N box is sliding down a ramp. I am in front of the ramp pushing uphill, so that the box slides with a constant velocity. The top of the ramp is 1.5 m above the bottom of the ramp and the ramp is 5.0 m long. As the box slides down, friction does work and 500 J are added to the thermal energy of the ramp and box. a. Calculate the work done by one external force in...
