u = u cos θ hati + u sin θ hatj ν = u cos θ hati Δ ν = ν - u

Q. A particle is fired with velocity u making angle $θ$ with the horizontal. What is the change in velocity when it is at the highest point

$u$ cos $θ$

$u$

$u$ sin $θ$

( $u$ cos $θ - u$ )

$u = u cos θ \hat{i} + u s in θ \hat{j}$
$ν = u cos θ \hat{i}$
$Δ ν = ν - u$

Q. A particle is fired with velocity u making angle θ with the horizontal. What is the change in velocity when it is at the highest point

u cos θ

u

u sin θ

(u cos θ−u)

u=ucosθi^+usinθj^​ ν=ucosθi^ Δν=ν−u
