3. Two blocks are connected by a light string that passes over an ideal pulley, as shown in the figure. The block of mass m₁ = 2.00 kg lies on a

horizontal surface and is connected to a spring of force constant k = 2.00 x 10² N/m. The coefficient of kinetic friction between the block of mass m₁ and the surface is Hk = 0.163. The system is released from rest when the spring is unstretched and the hanging block of mass m₂ = 4.00 kg falls a distance h before coming to rest, as illustrated in the figure. (a) Calculate this distance h. (b) Calculate the speed of the hanging block of mass m₂ after it has fallen a distance d = 0.180 m. (c) Calculate the minimum value of the coefficient of static friction between the block of mass m, and the surface that will prevent the system from moving again after it comes to rest. Is it reasonable? What do you conclude? k www.m mq h
