A block of mass m1 = 20.0 kg is connected to a block of mass m2 = 30.0 kg by a massless string that passes over a light, frictionless pulley. The 30.0-kg block is connected to a spring that has negligible mass and a force constant of k = 250 N/m.The spring is unstretched when the system is as shown in the figure, and the incline has a coefficient of friction of 0.2. The 20.0-kg block is pulled a distance d = 20.0 cm down the incline of angle of 30.0 degrees and released from rest. Find the speed of each block when the spring is again unstretched
