Suppose you stand on the floor of a train moving at constant speed in a straight line. If you jump straight upward, you will land
(a) at your original location
(b) slightly in front of your original location.
(c) slightly in back of your original location.
(d) in back of your original location a distance that depends on how high you jump.
The correct option for the statement "Suppose you stand on the floor of a train moving at constant speed in a straight line. If you jump straight upward, you will land".
Answer to Problem 10RAT
The correct option for the statement "Suppose you stand on the floor of a train moving at constant speed in a straight line. If you jump straight upward, you will land" is option (a).
Explanation of Solution
The relative speed is defined as the speed of an object concerning the other moving or fixed object. If two objects were moving in the same direction and with the same speed, then its relative speed is zero.
If a person is standing on the floor of a train moving at a constant speed in a straight line, then the relative speed of you and train is zero. Therefore, if a person jumps straight upward, you will land at your original place because of relative speed. From this, it is concluded that option (a) will be correct in the given options.
Conclusion:
Therefore, the correct option for the statement "Suppose you stand on the floor of a train moving at constant speed in a straight line. If you jump straight upward, you will land" is option (a).
