Question

A ball is projected horizontally with a velocity of 3m/s what is the velocity of ball after 0.4s

Answer 1

7.5 velocity after 0.4sec

Answer 2

hy......

friend.....

$v = 0 + [{9.8 x.4}] v [verical] = 3.92m/s v =[final]^{2} = [3.92]^{2} + [3]^{2} v = [final] = 4.93 m/s Angle = arctan(3/3.92) Angle =37.43 degrees downwards$

thankyou
