Question
Two projectiles are projected with the same velocity. If one is projected at an angle of 30o and the other at 60o to the horizontal, the ratio of maximum heights reached. is
Options
A.1 : 3
B.2 : 1
C.3 : 1
D.1 : 4
Solution
For maximum height
H =
H1 =
H1 : H2 = sin230o : sin2 60o =
= 1:3
H =
H1 =
H1 : H2 = sin230o : sin2 60o =
= 1:3Create a free account to view solution
