another quest. a small steel ball is dropped from a height of 2.5m into glycerin jar. it hits the surface of glycerin with certain velocity and sinks into the bottom by losing its 20% of its velocity at the surface. if the time taken to reach the bottom after it si dropped is 2 sec. and velocity in glycerin is lost at constant rate, then fiind the average velocity of the ball of journey

A lift whose cage is 3 m high is moving up with an acceleration of 2m/s2. A piece of stone is dropped from the top of the cage of the lift when its velocity is 8m/s. if g =10m/s2 then the stone wil reach the floor of the lift after how much time?
