A block of mass M = 10.0 kg is given an initial speed v0 = 2.10 m/s from height hi down a frictionless incline plane of angle θ = 75◦. After it reaches the bottom of the incline, it continues to slide on a horizontal surface of coeﬃcient of kinetic friction µk = 0.15. After sliding a distance d = 1.8 m along the horizontal surface, the block moves at a speed v = 7.00 m/s. Magnitude of acceleration due to gravity is g = 10 m/s2. 14 pt At what initial height hi on the plane was it released from? 5.A 2.50 m B 1.96 m C 2.23 m D 0.65 m E 2.41 m.

A) A bowling ball is given an initial speed v0 on an alley such that it initially slides without rolling. The coefficient of friction between ball and alley is µ. Find the speed of the ball’s center of mass vCM at the time pure rolling motion occurs. B) Since the frictional force provides the deceleration, from Newton’s second law it follows that aCM = µ g. Find the distance x it has traveled. When pure rolling motion occurs, vCM =...
