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
