A block of mass m₂ = 12.0 kg is connected to a block of mass m₂ = 36.0 kg by a massless string that passes over a light, frictionless pulley. The 36.0-kg block is connected to a spring that has negligible mass and a force constant of k = 240 N/m as shown in the figure below. The spring is unstretched when the system is as shown in the figure, and the incline is frictionless. The 12.0-kg block is pulled a distance h = 18.0 cm down the incline of angle 8 = 40.0° and released from rest. Find the speed of each block when the spring is again unstretched. m/s m/s = Vm2 = Tw
