Two bodies are projected with the same velocity. If one is projected at an angle of 30° and the other at an angle of 60° to the horizontal, the ratio of the maximum heights reached is
(1) 3 : 1
(2) 1 : 3
(3) 1 : 2
(4) 2 : 1
If the equation for the displacement of a particle moving on a circular path is given by \(\theta = 2t^3 + 0.5\) where θ is in radians and t in seconds, then the angular velocity of the particle after 2 sec from its start is:
1. 8 rad/sec
2. 12 rad/sec
3. 24 rad/sec
4. 36 rad/sec
A body is projected at such an angle that the horizontal range is three times the greatest height. The angle of projection is

(2)
(3)
