Question 6
A bullet is fired from a gun at 300 to the horizontal. The bullet remains in flight for 25 s before touching the ground. Calculate the velocity of projection. [g= 10 m s-2]
Observation
This question tested the ability of candidates to solve projectile questions. The performance was fair.
The expected answer is:
Calculation of velocity of projection of fired bullet
Time of flight T = 
25 = 
u = 250 m s-1
