A heavy particle is projected with a velocity at an angle with the horizontal into the uniform gravitational field. The slope of the trajectory of the particle varies as

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A
`V_(x)=U cos theta , V_(y)=U sin theta-"gt"`
`Tan alpha=(U sin theta- "gt")/(U cos theta),Tan alpha=(sin theta)/(cos theta)-(g/(U cos theta))t`
Comparing with `y=c-mx`
