what are the steps needed to solve this problem? can you please explain why and how?
A 65‐kg woman descends in an elevator that briefly accelerates at
0.20g downward. She stands on g a scale that reads in kg.
(a) During this acceleration, what is her weight and what does the
scale read?
(b) What does the scale read when the elevator descends at a
constant speed of 2.0 m/s?

-
(a) By W = mg - ma
=>W = m(g-a)
=>W = 65 x (9.8 - 0.20)
=>W = 624 N
(b) W = mg
=>W = 65 x 9.8
=>W = 637 N
=>W = m(g-a)
=>W = 65 x (9.8 - 0.20)
=>W = 624 N
(b) W = mg
=>W = 65 x 9.8
=>W = 637 N
