A projectile is fired with a velocity u at right angles to the slope, which is inclined at an angle `theta` with the horizontal. Derive an expression for the distance R to the point of impact.
.

A

`(2u^(2))/(g)tantheta`

B

`(2u^(2))/(g)sectheta`

C

`(u^(2))/(g)tan^(2)theta`

D

`(2u^(2))/(g)tanthetasectheta`

Text Solution

Verified by Experts

The correct Answer is:
A
`alpha= theta theta^(1)=90^(@)+theta theta^(1)-theta=90^(@)`
`R=(2u^(2)cos theta^(1) sin (theta^(1)-theta))/(g cos^(2) theta)`
