Question

A bullet is fired horizontally aiming at a target 60 m
away with a speed of 300 m/s. The gun should be
aimed above the target so that the bullet hits
the target.​

Answer 1

Answer:

time taken to travel 60m with 300m/s speed=1/5second

1/5 second should be the time taken by ball to drop vertically

h=at^2/2

h=1/5m

Answer 2

Answer:

Explanation:If fired horizontally,bullet will miss target by a height y=gx^2/(2u^2)

y=10×(60)^2/2×(300)^2=20cm

Therefore,it should be aimed 20cm higher.
