a block of mass 10 kg is initially at rest when it slides down a frictionless incline whose height is 10 m and is pitched at an angle of 30 degrees. At the bottom of the incline the mass encounters a horizontal surface that has a coefficient of kinetic friction of 0.4 with the mass. How far from the bottom of the incline will the mass come to a stop?
A block of mass m starts from rest and slides down from the top of a wedge of height h and length d. The surface of the wedge forms an angle of ? with respect to the horizontal direction.

A block of mass m = 2.26 kg slides down an α = 32.8 ° incline
which is h = 3.54 m high. At the bottom, it strikes a block of mass
M = 7.22 kg which is at rest on a horizontal surface, as seen in
figure below. (Assume a smooth transition at the bottom of the
incline.) If the collision is elastic, and friction can be ignored,
determine the speed of the smaller block after the collision.
