A 1.00-kg glider on a horizontal air track is pulled by a string at an angle 0. The taut string runs over a pulley and is attached to a hanging object of mass 0.500 kg as shown in Figure P5.40. (a) Show that the speed v of the glider and the speed v of the hanging object are related by v = uv, where u = z(23 - h,?)-1/2. (b) The glider is released from rest. Show that at that instant the acceleration a of the glider and the acceleration a of the hanging object are related by a = ua. (c) Find the tension in the string at the instant the glider is released for h, = 80.0 cm and 0 = 30.0. ho
