Question

the barrel of a gun is 1 metre long and it fires A bullet of mass 0.05 kg with the muzzle velocity of 400 ms -.now find 1) the acceleration and 2) forcre given to the bullet by the gun..​

Answer 1

Answer:

a = 80,000 m/s²

F = 4000 N

Explanation:

a = 80,000 m/s²

F = 4000 N

Explanation:

mass of the bullet , m= 0.05 kg

distance travelled d = 1m

Velocity with which bullet comes out of the gun i.e. muzzle velocity v = 400 m/s

Using  v²- u² =2as, u = 0

v²=2as,⇒a = v²/2s

a = (400×400)/ (2×1) =80,000 m/s²

Force acting on the bullet

F = ma = 0.05×80000= 4000N
