A block of mass (m = 12 kg) is attached at its top to a string that goes up and loops over a pulley. Theend of the string is then attached to a second block of mass (m = 16 kg) that hangs freely. The bottom ofthe 12 kg block is attached to a spring with spring constant (k = 120 N/m). This spring is then attached tothe floor.a) What is the stretch in the spring from its relaxed position?6) If the spring was detached from the 12 kg block, what would the acceleration of the two blocks be?

A block of mass m. m₁ 22.0 kg is connected to a block of mass m₂ = 28.0 kg by a massless string that passes over a light, frictionless pulley. The 28.0-kg block is connected to a spring that has negligible mass and a force constant of k = 200 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 22.0-kg block is pulled a distance h = 18.0 cm down the incline of angle 0 = 40.0° and released from rest. Find the speed of each block when the spring is again unstretched. m/s m/s V m1 V m2 = 0 = m₁ m₂ w
