Cart A weighing 120 lbs has a hanging mass B weighing 45 lbs attached to it by a 7 ft cable. The cart is free to slide along the frictionless track. If the system starts at rest with 0 = 45°, find: (a) The velocity of the cart at the moment when the mass is directly underneath it. (b) The velocity of the mass at this same moment.
