A child jumps on a trampoline. He stretches the trampoline downward when he lands on it. He comes to a short stop when the trampoline can't stretch any farther. He then bounces upward again. What is happening to his kinetic energy as the trampoline stretches and slows him? His gravi- tational potential energy? The elastic potential energy of the trampoline? What is happening to the total of these three?

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?
