Question

A person of mass 50kg rides an elevator whose motion consist of
(a)acceleration upward at 3m/s
(b)constant velocity
(c)acceleration downward at 3m/s

Given that g=9.8m-2 down, find the person's weight during each stage of the lift ride?
(a) 3 m/s is not an acceleration rate.
You probably mean 3 m/s^2.

(b) Weight = M*g = 490 N

(c) 3 m/s is not a deceleration rate.
