Question 3 of 14
3. Question
1 pointsA woman stands on top of a moving railroad car and tosses a ball straight up in the air. If there is no air resistance, where will the ball come back down?
Correct
That’s correct
Incorrect
The ball would return to the woman’s hand, as its inertia (granted by the forward motion of the railroad car) would be unchanged by the vertical acceleration of her hand
