of projection. If times of flight in two cases are T1
and T2 , then velocity of projection of the projectile is​

Answer 1

Answer:

thank you , comment, follow me

Step-by-step explanation:

t1+t2=t3

Answer 2

Answer:

A projectile with equal speed of projection can have the equal range ′R′ for two angles of projection. If t1 and t2 be the time of flight in two cases, then the product of two time of flight (t1.
