what is the mass m of the elevator? use g=10m/s2 for the magnitude of the acceleration of gravity.

what is the mass m of the elevator? use g=10m/s2 for the magnitude of the acceleration of gravity.

Answer:

Let the acceleration the elevator was going down with be a,

Since the mass will remain constant,

we have,

M(g-a) = 1/3 Mg

g- a = 1/3 g

a=g-1/3 g

a= 2/3 g
