Projection Under uniform Acceleration

Question

A bullet is to be fired with a speed of 2000 m s^-1 to hit a target 200 m away on a level ground. If g = 10 m s^-1 the gun should be aimed:

Easy

A

directly at the target
B

5 cm below the target
C

5 cm above the target
D

2 cm above the target

Solution

Time taken = $\frac{200}{2000}$ = 0.1 s, so aim should be $\frac{1}{2} {gT}^{2}$ above the target.
