As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h.
As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h. When the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 15.0 cm that has a coefficient of kinetic friction μk = 0.520. Find h such that the block's speed after crossing the rough patch is 4.20 m/s.
An object with a mass m = 4.00 kg is attached to the end of a spring, and the spring is stretched an amount xi = 4.60 cm and then released. If the force constant for the spring is k = 520 N/m, determine the speed of the mass as it passes through the equilibrium position the first time for the following two cases.
(a) The horizontal surface the object is sliding along is frictionless.
(b) The coefficient of kinetic friction between the horizontal surface and the object is μk = 0.250.

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...
