a particle is projected from a point A with a velocity v at a angle theta {upward} horizontal. at a certain point B it moves at a right angle to its intial direction it follows that {A}velocity of the particle at B is v {B}velocityof that particle at B is v cos theta {C} velocity of the particle atB is vtan theta {D}the time of flight from AtoB is v/gsintheta
