A particle is projected with velocity v at an angle `theta` aith horizontal. The average angle velocity of the particle from the point of projection to impact equals

Explanation

`v_x = u_x _ a_x t`
`0 = u cos theta + (-g sin prop) T`
`T = (u cos theta)/(g sin prop) = (u cosec theta)/(2 g)`
`(cos theta)/(sin prop) = (1)/(2 sin theta)`
or `prop = 2 theta`.
