Two students perform an experiment with a train and a ball. Michelles rides on a fltcar pulled at 7.85 m/s by a train on a straight, horizontal track; Gary stands at rest on the ground near the tracks. When michelle throws the ball with an initial angle of 57° above horizontal, from her point of view, Gary sees the ball rise straight up and back down above a fixed point on the ground. A. Did michelle throw the ball toward the front of the train or toward the rear of the train? Explain b. What was the initial speed of Michelle’s throw? c. What was the initial speed of the ball as seen by Gary?
