Answer:
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.
The first one will be 220N
Newton's second law of motion can be used to calculate weight.
