A freight train car is moving at a constant speed with respect to the ground of Vcg. A man standing on a flatbed car throws a ball into the air and catches it as it falls. Relative to the flatbed car, the initial velocity of the ball is Vibc straight up. a. What are the magnitude and direction of the initial velocity of the ball as seen by a second man standing on the ground next to the track? b. How much time is the ball in the air according to the man on the train? According to the man on the ground? Mathematically prove your two answers. c. What horizontal distance has the ball traveled by the time it is caught according to the man on the train? According to the man on the ground? d. What is the minimum speed of the ball during its flight according to the man on the train? According to the man on the ground? e. What is the acceleration of the ball according to the man on the train? According to the man on the ground
