Baseball player A bunts the ball by hitting it in such a way that it acquires an initial velocity of 1 m/s parallel to the ground. Upon contact with the bat, the ball is 1.5 m above the ground. Payer B wishes to duplicate this bunt, in so far as he also wants to give the ball a velocity parallel to the ground and have his ball travel the same horizontal distance as player A's ball does. However, player B hits the ball when it is 1.6 m above the ground. What is the magnitude of the initial velocity that player B's ball must be given?
horizontal distance is the same.
but time in air for any fallingobject is sqrt(2h/g)
