Q1. A 37-kg girl is bouncing on a trampoline. All through a certain interval after she leaves the surface of the trampoline, her kinetic energy decreases to 215 J from 430 J. How high does she rise during this interval? Avoid air resistance.

Q2. A car rests on the slanted ramp leading into car-transporter trailer. The car's brakes and transmissions locks are released; only the cable attached to the car and to the frame of the trailer prevents car from rolling backward off the ramp. If the car's weight is w, find out the tension in the cable and the force with which the ramp pushes on the car tires.
