a body is projected with an initial velocity 20 m per second at 60 deg

1.	a body is projected with an initial velocity 20 m per second at 60 degrees to the horizontal. It's initial velocity vector is,
Answer» Its INITIAL VELOCITY in the x-direction is 20cos60° =20/2=10m/s. initial velocity in y direction=20sin60°=20√3/2=10√3m/s. so velocity VECTOR is 10I^ +10√3j^.
