A 1.00-kg glider on a horizontal air track is pulled by a string at angle &. The taut string runs over a light pulley at height h0 = 40.0 cm above the line of motion of the glider. The other end of the string is attached to a hanging mass of 0.500 kg as in Fig. P5.65. (a) Show that the speed of the glider vx and the speed of the hanging mass vy are related by vy = vx cos θ. The glider is released from rest when θ = 30.0°. Find (b) vx and (c) vy when θ= 45.0°. (d) Explain why the answers to parts
