Question

ans this phys question wid proper explanation.

Answer 1

Mass of gun, M = 10kg

Mass of each bullet, m= 20g = 0.02kg
Velocity of each bullet = 300 m/s
Number of bullets per second , n = 4

Force needed to hold gun while firing is the rate of change in momentum.

rate of change in momentum = change in momentum per second = n×mv = 4×0.02×300 = 24 N

Thus force required to hold the gun in position is 24 N.

Force needed to hold gun while firing is the rate of change in momentum.

rate of change in momentum = change in momentum per second = n×mv = 4×0.02×300 = 24 N

Thus force required to hold the gun in position is 24 N.
