The arms of the top acrobat (in yellow), together with the weight of his head and shoulders, provide a downward force at a distance of 31 cm from Part A the pivot point to balance the torque produced by his lower body. If the lower body of the top acrobat is modeled as a 50-kg mass at a distance of 43 cm from the pivot point, how much force must the arms and upper body produce?

Problem 4: Speed deamplifier. In the figure above on the right, block 1 of mass m1 slides along an x-axis on a frictionless floor at speed 4 m/sec.Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass mz = 4m1. What then is the speed of block 3? Answer: 16 m/sec or 1.78 m/sec.
