A 1.00-kg block (M) is on a frictionless, 20o inclined plane. The block is attached to a spring (k = 25 N/m) that is fixed to a wall at the bottom of the incline. Alight string attached to the block runs over a frictionless pulley to a 40.0-g suspended mass. The suspended mass is given an initial downward speed of 1.50 m/s. How far does it drop before coming to rest? (Assume the spring is unlimited in how far it can stretch.)
