A particle is projected from the ground with velocity `u` at angle `theta` with horizontal.The horizontal range,maximum height and time of flight are `R,H` and `T` respectively.Now keeping `u` as fixed, `theta` is varied from `30^(@)` to `60^(@)`.Then

A particle is projected from the ground with velocity u making an angle theta with the horizontal. At half of its maximum heights,

A particle is projected from the ground with velocity u at angle theta with horizontal. The horizontal range, maximum height and time of flight are R,H and T respectively. They are given by, R = (u^(2)sin 2 theta)/(g),H = (u^(2)sin^(2)theta)/(2g) and T = (2usin theta)/(g) Now keeping u as fixed, theta is varied from 30^(@) to 60^(@) . Then,
