A ball is projected horizontally with a velocity 4g m/s from height 18 meter. What is the velocity of body at t = 3 sec?

Given,

A ball is projected in horizontal direction with velocity 4g m/s.Â

Height from which the ball is projected = 18 mÂ

Â  Â  Â  Â  Â  Â  Â  Â  Â  Â  Â Â

At time t=3 s, horizontal and vertical component of velocity is given by,Â

Therefore, magnitude of velocity is given by,Â

v =Â Â

The angle that the velocity vector makes with horizontal is,
