Problem 1 (20 points) Two blocks, A and B, with mass 44.2 kg and 87.6 kg, respectively, are connected by a light string. The pulley is frictionless and of negligible mass. The coefficient of kinetic friction between block A and the table is pk = 0.18. Determine the final speed of block B after it descends through 1.48 m downward. Assume the system starts from rest. Neglect static friction between block A and the table just assume there is kinetic friction as soon as block A and block B are released from rest. Problem 2 (20 points) Bead A, which is 0.235-kg, slides on a frictionless wire with an initial speed of 3.10 m/s at point 1. Bead A slides down a height of 0.502 m where it collides elastically with bead B, which is initially at rest, and which has a mass of 0.410-kg. Find the maximum height bead A rises after it collides with head B. h: 0.519: m Problem 3 (20 points) A massless spring of constant k = 105.2 Nlm is xed on a level frictionless track. A block of mass m = 0.225-kg is pressed against the spring and compresses it a distance d = 0.153 m. The block, which is initially at rest, is then released and travels toward a circular loop-the-loop of radius R. The entire track and the looptheloop are frictiOnless. Determine the maximum radius Rm, of the loop-theloop, that enables the block to just make it through the top of the loop-the-loop at point C
