Question

what will be the weight of man if an elevator is moving downward with an acceleration of 4.9ms^-2?

Answer 1

Answer: 4.9m N or ½ of original weight.

Explanation: If the elevator is going down, the man will feel lighter.

So net acceleration will be g - a = 9.8 m/s² - 4.9 m/s² = 4.9 m/s²

We know that initial weight = ma = 9.8m N

Final weight = ma = 4.9m N

So his weight will be ½ of his original weight.
