A projectile is fired from the ground level with a velocity of 300ms-1 at an angle of a 30o to the horizontal.
Calculate the time taken to reach the maximum height?
[g = 10ms-2]
30s
20s
25s
15s
Correct answer is D
The total time of flight is given as
T=2usinθg
Hence, time to maximum height is half of the total time of flight,
t = usinθg
= 300sin3010 = 15s
