Question

a bullet is fired with a speed of 10^3 ms^-1 in order to hit a target 100m away . If g=10 s^-2 , the gun should be aimed at
a) directly towards the target
b) 5 cm below the target
c) 5 cm above the target
d) 15 cm above the target​

Answer 1

Answer:

c

Explanation:

T = d/v = 100/1000 = 0.1s

Distance covered by bullet vertically downwards in that time = s = 0.5 * 10 * 0.1*0.1= 0.05 m

So, the bullet should be fired 5cm above the target.

Answer 2

Explanation:

c) 5 cm above the target
