Question: A freight train is moving at a constant speed of 10 m/s. A ma n standing on a flatcar throws a ball into the air

A freight train is moving at a constant speed of 10 m/s. A ma n standing on a flatcar throws a ball into the air and catches it as it falls. Relative to the flatcar, the initial velocity of the ball is 15 m/s straight up.

(a) What are the magnitude and direction of the initial velocity of the ball as seen by a second man standing next to the track?

(b) How long is the ball in the air according to the man on the train? According to the man on the ground?

(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?
