A moves downward a distance of 3.6 ft, and mass B moves a distance x. What is the value of x 2. Find the speed of mass B for a given speed of mass A The system is released from rest and mass A moves downward at a constant speed of 8.0 ft/s. What is the magnitude of the upward speed of mass B? 3.Find the acceleration of mass B for a given acceleration of mass A The system is released from rest and mass A moves downward with an acceleration of 1.2 ft/s^2. What is the magnitude of the upward acceleration of mass B?
