A 1.40-kg block is on a frictionless, 25 ∘ inclined plane. The block is attached to a spring (k = 30.0 N/m ) that is fixed to a wall at the bottom of the incline. A light 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 1.20 m/s .
How far does it drop before coming to rest? (Assume the spring is unlimited in how far it can stretch.)
