A 3 kg mass object is pushed 0.6 m into a spring with spring constant 210 N/m on a frictionless horizontal surface. Upon release, the object moves across the surface until it encounters a rough incline. The object moves UP the incline and stops a height of 1.5 m above the horizontal surface. 210 N/m Pic #1 0.6 m 3 kg (a) How much work must be done to compress the spring initially? (b) Compute the speed of the mass at the base of the incline.
