Questions
A projectile can have the same range R for two angles of projection. If t1 and t2 be the times of flights in the two cases, then the product of the two times of flight is proportional to
detailed solution
Correct option is A
Here t1=2usinαg and t2=2usin90∘−αg…(1)Now t1t2=4u2g2sinαcosαWe know thatR=u2sin2αgFrom eqs. (1) and (2), we get t1t2=2Rg∝RTalk to our academic expert!
Similar Questions
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.
