Questions
Two identical projectiles are fired simultaneously as shown from the ground with the same magnitude of velocity and at the same angle with respect to the horizontal. The two projectiles collide at the highest point ‘B’ and coalesce. After how much time of firing them, they reach the ground ?
detailed solution
Correct option is C
Conserving momentum at the highest point B, (m + m)v =m x ucosα + m(-ucosα) ⇒ v = 0T = Time of flight of each projectile = 2usinα/g.t = Time of free fall of the combined man =Talk to our academic expert!

Assertion : When the velocity of projection of a body is made n times, its time of flight becomes n times.
Reason : Range of projectile does not depend on the initial velocity of a body.
