A ball is thrown upward in the air by a passenger on a train that is moving with constant velocity, (a) Describe the path of the ball as seen by the passenger. Describe the path as seen by a stationary observer outside the train, (b) How would these observations change if the train were accelerating along the track?

(a)

To determine
The path of the ball as seen by the passenger and as seen by a stationary observer outside the train when the ball is thrown upwards from a train moving with constant velocity.

Explanation

When a ball is thrown upwards from a moving train, the ball acquires an initial velocity equal to the velocity of the train. Thus, the actual motion of the ball will be a projectile motion...

(b)

To determine
The path of the ball when the ball is thrown upwards from a train accelerating along the path.
