Question

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.

Answer 1

Correct Answer - A
`y = x tan theta - (gx^2)/(2u^2 cos^2theta)`
`:. (dy)/(dx) = (tan theta)-(g/(u^2cos^2theta))x`
`:. (dy)/(dx)` versus x graph is a straight line with negative
slope and positive intercept.
