Problem 1 (20 points) Two blocks, A and B, (with mass 23.0 kg and 82.0 kg, respectively), are connected by a light string, as shown in the figure below. The pulley is frictionless and of negligible mass. The coefficient of kinetic friction between block A and the incline is MK = 0.370. Assuming the system starts from rest after being gently nudged (assume initial velocity of both blocks is zero) block A moves from C to D, a distance of d = 15.0 m along the horizontal table. Determine the speed of block A when it reaches point D. 23.0 kg A D B 82.0 kgProblem 2 (20 points) A ball of mass m = 0.672 kg is sitting on top of a spring which is compressed by d = 15.8 cm. The spring constant is 1050 N/m. Neglect any losses to friction or air resistance. V= 0 h L... d V =0 (a) (10) Find the speed of the ball just as it passes by the equilibrium point of the spring. (b) (10) Find the maximum height, h, which is measured above the equilibrium point of the spring, that is reached by the ball
