Amy is at basketball practice. she is about to shoot a free throw. when she releases the ball the ball will not have kinetic energy but will have potential energy. the ball will have kinetic energy but will not have potential energy. the ball will have kinetic energy and potential energy. the ball will have neither kinetic energy nor potential energy.

To practice problem-solving strategy 10.1 for energy conservation problems. a sled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slides a distance d1 down the slope and then covers the distance d2 along the horizontal terrain before stopping. find the coefficient of kinetic friction μk between the sled and the ground, assuming that it is constant throughout the trip.
