Stone A is dropped but stone B and C are...

Stone A is dropped but stone B and C are projected horizontally `(u_(C)gtu_(B))` from top of tower of height h. then find out
(i) Which stone will reach the ground earlier
(ii) Relation between vertical velocity of stones when they hit the ground.

Text Solution

Verified by Experts

The correct Answer is:
(i) All stones will teach the ground at the same instant `t=sqrt((2h)/(g))`
(ii) same for all `v_(y)=sqrt(2gh)`
