Question

A projectile is thrown with a speed v at an angle 0 with
the vertical. Its average velocity between the instants
it crosses half the maximum height is
(A) v sin , horizontal and in the plane of projection
(B) y cos 0, horizontal and in the plane of projection
(C) 2v sin 0, horizontal and perpendicular to the plane
of projection
D) 2v cos , vertical and in the plane of projection.​

Answer 1

0

0

0

2vcos

as the angle is 0
