Question

A bullet with a muzzle velocity 10 Route 10 m/s is to be shot at a target 50 m away in the same horizontal line at a height above the target must be the life will be aimed so that the bullet will hit the target is

Answer 1

Answer:

Time taken by bullet to reach the target

T = Distance / Speed

= 50 / 10√10

= √2.5 seconds

Height above the target should be

H = 0.5gT^2

= 0.5 × 10 × (√2.5)^2

= 5 × 2.5

= 12.5 m

Height above the target should be 12.5 m
