Answer to Question #154488 in Physics for Natnale

Question

A body is projected at an angle of 53°, with the horizontal ,with velocity of 30m/s. What the angle(direction) of velocity vector is as measured from horizontal , when the projectile at it's maximum point on it's trajectory ?

Answer 1

When the projectile at its maximum point on its trajectory, the vertial component of its velocity is zero. Thus, its velocity is directed along the horizontal x-axis. Hence, the angle of velocity vector as measured from horizontal is zero.

Answer. $0\degree$.
