Trajectories of two projectiles are shown in the figure. Let T1 and T2 be the time of flights and u1 and u2be their speeds of projection. Then -

A

T2> T1

B

T1> T2

C

u1> u2

D

u1< u2

Answer

u1< u2

Explanation

Solution

Q Both projectiles have same height

\ (u sin q)1 = (u sin q)2 ̃ T1 = T2

But range is more for 2nd body.

\ (u cos q)2 > (u cos q)1 ̃ u2 > u1
