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

A

`u cos theta`

B

u

C

`u sin theta`

D

`u cos theta -u`

Text Solution

Verified by Experts

The correct Answer is:
C
`vec u =ucos theta hati +u sin theta hatj`
`vec v =u cos theta hati, vec (Delta v) =vec v- vec u`
