Chelsea went for a walk. At the beginning of her walk, she was traveling 2.3 m/s. Then she began to jog to reach a maximum speed of 4.2 m/s over a 15 second period. Assume that Chelsea’s acceleration was constant.

A ball is thrown straight upward and rises to a maximum height of 18.0 m above its launch point. At what height above its launch point has the speed of the ball decreased to one-half of its initial value?

You observe an articial satellite orbiting the earth. You estimates it is at an altitude h = km above the earth's surface and has a mass m = 3500 kg. You wish to calculate when the satellite will be back in the same position. From the second law of motion and the gravitational force law,...
