What is the average velocity of a projectile between the instants is crosses half the maximum height? It is projected with a speed u at an angle θ with the horizontal - (A) usinθ  (B) ucosθ  (C) utanθ  (D) u

Tardigrade Admin · Accepted Answer

During the displacement of the body from

A

to

B

, the vertical component of velocity has no effect. As the horizontal velocity of the projectile remain same during this displacement, average velocity of projectile for this displacement will also be same as magnitude of constant horizontal velocity of projectile. Average velocity of projectile is given as

< V >= u cos θ

.

$u s in θ$

$u cos θ$

$u t an θ$

$u$
