Q1. A 1.00 kg glider on a horizontal air track is pulled by a string at an angle θ. The taut string runs over a pulley and is attached to a hanging object of mass 0.500 kg . (a) Show that the speed vx of glider and the speed vy of the hanging object are related by vx = uvy, where u = z(z2-h02)-1/2. (b) The glider is released from rest. Explain that at that instant the acceleration ax of the glider and the acceleration ay of the hanging object are related by ax = uay. (c) Find the tension in the string at the instant the glider is released for h0 = 80cm and θ = 30.0°.

Q2. A 5578 physics student stands on a bathroom scale in an 832 (including the student) elevator that is supported by a cable. As the elevator starts moving, scale reads 431. A) Find the magnitude of acceleration on the elevator? B.) what is the acceleration if = scale reads 601N? C.)What is the tension in = cable in part A? D.)What is the tension in = cable in part D?
