Question

the body is projected with velocity U making an angle theta with the horizontal its velocity when it is perpendicular to the initial velocity vector is​

Answer 1

Explanation:

the body is projected with velocity U

so,As the angle of projection is theta with horizontal

so, let take componants of U

as U sin theta and U cos theta

along them the U sin theta is the componant perpendicular toh the to the Direction Of U

so ans is U sin theta
