Consider the system shown in the figure right, where two blocks m1=5 kg, and m2=10 kg are connected to each other
Consider the system shown in the figure right, where two blocks m1=5 kg, and m2=10 kg are connected to each other by a string that passes through a massless pulley. The stiffness constant of the spring attached to m1 and the wall is k=120N/m and the coefficient of kinetic friction between m1 and the surface is given to be μk=0.2. If the system is released from rest when the spring is at its equilibrium length and m2 is at a height of h=1m from the ground,
a) find the speed of m2 right before it hits the ground.
b) How much mechanical energy is lost from the moment the system is released till m2 hits the ground?
c) If the pulley had a significant mass, how would your answer to part a) change? Would you get a smaller or a larger speed? A very short explanation without any calculation is enough.

Two blocks m1 and m2 with masses 50 kg and 100 kg respectively are connected by a string over a pulley that is frictionless with negligible mass. The 50 kg block slides on a 37 degree incline that has a coefficient of kinetic friction of 0.25. This block is also attached to a wall at the base of the incline by an ideal spring that has a spring coefficient of 100 N/m. The system is released from rest with a...
Two blocks with mass M1 and M2 are arranged as shown with M sitting on an inclined plane
Two blocks with mass M1 and M2 are arranged as shown with M sitting on an inclined plane and connected with a massless unstretchable string running over a massless, frictionless pulley to M2, which is hanging over the ground. The two masses are released initially from rest. The inclined plane has coefficients of static and kinetic friction μs and μk respectively where the angle θ is small enough that mass M1 , would remain at rest due to static friction if...
