Two bodies are projected from the same point with equal velocities in such a directions that they strike on the same point on a plane whose inclination is `beta`. If `alpha` is the angle of projection of the first , the ration of there times of flight is

Two bodies are projected from the same point with equal speeds in such directions that they both strike the same point on a plane whose inclination is beta . If alpha the angle of projection of the first body with the horizontal , show that the ratio of their time of flights is (sin (alpha - beta))/(cos alpha)

Two bodies are projected from the same point with equal speeds in such directions that they both strike the same point on a plane whose inclination is beta . If alpha the angle of projection of the first body with the horizontal , show that the ratio of their time of flights is (sin (alpha - beta))/(cos alpha)

A number of particles are projected from a given point with equal velocities in different directions in the same vertical plane. At any instant they will lie on

Two bodies are projected from the same point with same speed in the directions making an angle alpha_(1) and alpha_(2) with the horizontal and strike at same point in the horizontal plane through a point of projection. If t_(1) and t_(2) are their time of flights.Then (t_(1)^(2)-t_(2)^(2))/(t_(1)^(2)+t_(2)^(2))
