A ball is dropped from rest from a tower of height of 5m. As a result of the wind it lands at a distance 6m from the bottom of the tower as shown. Assuming no air resistance but that the wind gives the ball a constant horizontal velocity v. Find value of v in m/s.

Dear student

Time to reach on land be t
t = sqrt ( 2*h/g)
t= 1 sec

Horizontal distance 6 m = v *t
6/1 = v = 6 m/s
