a person standing on the floor of an elevator , drops a coin . the coin reaches the floor of the elevator in time t1 if the elevator is stationary and in time t2 if it is moving uniformly then a: t1=t2b: t1
See relative velocity for the ball in both case with respect to lift would be zaro and acceleration relative to lift would be g.
by applying second equation of motion
h is the height of lift
from here u will get the time and u will see it will be same for both the cases as a and h are same.
