A block of mass m =0.25 kg at rest on a rough surface compresses a spring of spring constant k= 81 by x= 19 cm. When the block is released, the block slides on the rough surface with coefficient of kinetic friction of u= 0.25 for distance d= 0.5 m before it reaches a frictionless incline of angle 0 = 21°, 1. What is the potential energy of the spring when the spring is compressed by 19 cm: Usonng %3D 2. What is the speed of the block at the bottom of the incline (after having slided for d = 0.5 m:) v = 3. What is the maximum height the box can reach on the frictionless incline: h max %3D Check A block of mass m =0.25 kg at rest on a rough surface compresses a spring of spring constant k= 81 by x= 19 cm.
