A ball starts at rest on the top of a ramp. This amp accelerates the ball at a rate of 1.5 m/s. The ball takes 3s to roll down the ramp and then hits a patch of rough flat ground. On the ground, the ball accelerates at a rate of -5m/s until it stops. How long after the ball reaches the ground does it take for the ball to stop? Draw a diagram of the scenario labeling the information given in the problem Also label the boundary condition of this problem and solve the problem as well. Use vi for initial velocity and vf for final velocity.

A pool ball is released from rest at the top of a 1m high ramp. The ramp makes an angle of 34 degrees with the horizontal. The pool ball rolls to the bottom of the ramp and then smoothly continues to roll up the adjacent ramp that is .5m high and makes an angle of 12 degrees with the horizontal. Calculate the velocity of the pool ball as it reaches the very end of the 12 degree ramp.

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...

A 7.4kg block starts 1.2m above the ground, at the top of a frictionless ramp. At the bottom of the ramp is a flat stretch of rough (ulk = 0.15) ground 3.0m long. After sliding 3.0m, the ground becomes frictionless, and the block hits a spring (k = 1.6kN/m). a. Calculate the speed of the block at the bottom of the ramp. m b. Calculate the speed of the block just before it hits the spring. c. Calculate how far...
