Question

A body is projected horizontally from a height with a velocity of 9.8 m/s what time elapses before horizontal and vertical velicities become equal?

Answer 1

hey frnd...

given that

initial velocity = u = 0

and final velocity = 9.8 m/sec

g = 9.8 m/sec^2

now using the motion equation

v= u+at

9.8= 0+9.8t

t= 1 sec
