15-8* A 20-kg block is pushed up an inclined plane by a horizontal force F of 200 N as shown in Fig. P15-8. The ki- netic coefficient of friction between the inclined plane and the block is μk = 0.10. If v = 0 and x = 0 when t = 0, de- termine a. The acceleration of the block. b. The time required for the block to travel 15 m up the incline. c. The velocity of the block after it has traveled 10 m up the incline. F 30° Fig. P15-8
