A body is projected upwards. What is its initial velocity at maximum height?

A body when projected up with an initial velocity u goes to a maximum height h in time t and then comes back at the point of projection. The correct statement is :

A body A is projected upwards with a velocity of 90m//s . The second body B is projected upwards with the same initial velocity but after 4 sec. Both the bodies will meet after

A body is just dropped from a height. What is its initial velocity?

A body X is projected upwards with a velocity of 98 ms^(-1) , after 4s, a second body Y is also projected upwards with the same initial velocity . Two bodies will meet after

A body X is projected upwards with a velocity of 98 ms^(-1) , after 4s, a second body Y is also projected upwards with the same initial velocity . Two bodies will meet after

A body X is projected upwards with a velocity of 98 ms^(-1) , after 4s, a second body Y is also projected upwards with the same initial velocity . Two bodies will meet after
