A block is released from rest at the top of an inclined 6.20 m
long. The angle of the incline with respect to the horizontal
direction is and the coefficient of kinetic friction between the
block and the surfaces (incline and horizontal) is . The block
slides along the incline with constant velocity and continues
moving along the horizontal surface until it comes to rest. Using
the work-energy theorem, Determine:

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...
