Question

A projectile is projected with speed u at an angle theta with horizontal the average velocity of the projectile between the instant it crosses the same level is

Answer 1

Answer:

$u \: cos \: theta$

Explanation:

From the figure, it can be said AB is horizontal. So there is no effect of vertical component of the velocity during this displacement. So because the body moves at a constant speed of ‘u cos θ' in horizontal direction. The average velocity during this displacement will be u cos θ in the horizontal direction.
