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)/g tan theta`

B

`(2u)/g sec theta`

C

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

D

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

Text Solution

Verified by Experts

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