Question

A 20.0 kg block is connected to a 30.0 kg block by a string thatpasses over a light, frictionless pulley. The 30.0 kg block isconnected to a spring that has negligible mass and a force constantof 300 N/m, as shown in the figurebelow. The spring is unstretched when the system is as shown in thefigure, and the incline is frictionless. The 20.0 kg block ispulled 20.0 cm down the incline (sothat the 30.0 kg block is 40.0 cmabove the floor) and released from rest. Find the speed of eachblock when the 30.0 kg block is 20.0 cm above the floor (that is,when the spring is unstretched).
