Question

The block shown in Fig. 4-59 has mass m=7.0 kg and lies on a fixed smooth frictionless plane tilted at an angle (theta)= 22.0 degrees to the horizontal. (a) Determine the acceleration of the block a step it slides down the plane. (b) If the block starts from rest 12.0m up the plane from its base, what will be the block’s speed when it reaches the bottom of the incline?
