Two students perform an experiment with a train and a ball. Student A rides on a flatcar pulled at 8.35 m/s by a train on a straight, horizontal track. Student B stands at rest, on the ground near the tracks. Student A throw ball with an initial angel of 65 degrees above horizontal, from her point of view. Student B sees ball rise straight up and back down from a fixed point on the ground.
1. What was the initial speed of ball seen by Student B?
2. What was the initial speed of Student A's throw?
3. Did Student A throw the ball toward front or toward rear of train? Describe.
