A ball is thrown upward in the air by a passenger on a train that is moving with constant velocity. Describe the path of the ball as seen by the passenger. Describe the path as seen by a stationary observer outside the train.

The path of the motion seen by passenger on a train to be in a straight line upwards and down straight down in the same path.

The path of motion seen by an observer outside the train appears to be in a parabolic path like a projectile.

The path of motion of the ball thrown into upward into the air appear differently to the passenger on a train moving at a constant speed and to the stationary observer.

The passenger on a train moving at a constant speed observes the path of the motion to be in a straight line upwards and down straight down in the same path.

The path of motion seen by an observer outside the train appears to be in a parabolic path like a projectile.

a) For the passenger the ball is seen to go up in a straight line path, and fall back to the hands of the passenger in a straight line path.

b) For a stationary observer on the ground, the ball is seen to take a parabolic path from when it is thrown up to when it fall down back on the palms of the passenger.

Explanation:

If a ball is thrown up in a vehicle moving with a constant velocity, the ball will be seen as the passenger, who is on the same frame of reference as the ball, to go up and down in a vertical straight line path. For an observer on the ground, this is different, as the ball is seen to to have both a relative vertical and horizontal component of motion, making the ball take a parabolic path from the time it was thrown, to when it falls back to the hands of the passenger.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
