A particle is projected from a point a with velocity v at an angle θ upward with the horizontal at a certain point P it moves at right angle to its initial direction it follows that​

Answer 1

Answer:

Explanation:

A particle is projected from a point A with a velocity V at an angle 0 (upward) with the horizontal. At a certain point B, it moves at right angle to its initial direction. It follows that 0 speedof the particle at B is V 0 speed of the particle at B is V cos 0 0 speedof the particle at B is V tane 0 the time of flight from A to B is – gsind
