The Drill Directions: For each of the following situations, determine: (a) the acceleration of the block down the plane (b) the time for the block to slide to the bottom of the plane In each case, assume a frictionless plane unless otherwise stated; assume the block is released from rest unless otherwise stated.

5. h = 10 m 20 m 6. 20 m Vo = 5.0 m/s down the plane 7. . 20 m vo = 5.0 m/s up the plane 8. m 20 m 250 m = 30 kg H = 0.30 vo = 3.0 m/s up the plane
