the following statements about the motion of the elevator could be true at time t2 is
c. The elevator is moving downward at constant speed.
Explanation:
- Under given situation, the elevator is at rest and the reading on the scale is 500N.
- After some time t2, the person is still standing on the scale and the reading on the scale is 400N .
- It is because if you stand on a scale in an elevator which is accelerating upward, your body will feel heavier because the elevator's floor pressure which presses harder on your feet, and this is why the scale will show a higher reading than the time when the elevator is at rest.
- Similarly on the other hand, when the elevator accelerates downward, your body will feel lighter. The force which is exerted by the scale is called as the apparent weight; which means it does not change with constant speed.
- Applying Newton's second law, which concludes about this particular statement about force exerted on a body when at rest and when in motion.
