A particle is fired from ground with speed u making an angle theta with the horizontal. The speed of the particle just before hitting the ground will be

Answer»

Answer:

let,

VELOCITY=v

Time taken by projectile=t

initial velocity =u

Angle =theta

we know ,

when time FLIGHT is given,

u= tg/2sin(theta)

when Horizental range is given,

u=Rg/sin(2theta)
