Tom (65 kg) is standing on a scale in an elevator holding an apple. The elevator begins to accelerate downwards at 2.4 m/s2.
(a) What does the scale read during this acceleration?
(b) What is the acceleration of the apple with respect to Tom holding the apple?
2.4 m/s^2 (same as the elevator's acceleration)
am i right?
(c) Then as tom is accelerating up, he drops the apple. What is the acceleration of the apple with respect to you (i.e. an outsider looking on)?
(d) What is the acceleration of the apple with respect to Tom?
(e) What would the scale read if the elevator accelerated downward at 2.4 m/s2?
