Part A & D

(4%) Problem 22: A block of mass m is located on an inclined plane that makes an angle 0 with the horizontal. The coefcient of kinetic friction between the block and the inclined plane is it] . The block presses against, but is not attached to, a spring with constant k1 . When the spring is at its equilibrium position, the block is at a height h above the ground, as shown. The initial position of the block, from which it is released, is a bit further up the inclined plane such that the spring is initially compressed by Ax. At the bottom of the inclined plane is a horizontal plane with a different coefcient of friction, it: , for the rst distance, cl, after which the surface is frictionless, and the equilibrium position of a spring with constant k2 is encountered - .' lilctwpt'rtiuxmn Q 25% Part (3) Suppose that numeric values are chosen such that the block comes to rest before reaching the bottom of the ramp. Let x be the distance traveled from the equilibrium position of the block towards the bottom of the ramp. Enter an expression for x.

The horizontal surface then becomes frictionless, at the equilibrium position of a spring with constant k2 - 7. 5 N/m. Calculate the distance As in meters ,by which the spring is compressed as the block comes to rest
