Question

N bullets eqch of mass m are fired with velocity v m/s at the rate of n bullets per sec upon a wall . Ifc the bullets are stopped by wall , The reaction force offered by wall to bullets is ?

Answer 1

Heya......!!!

Mass of each bullet = m Kg
Velocity of each bullet = v m/s

mass of n bullet = mn
so ,, Change in momentum
=>> ( 0 - mnv )

momentum final = 0
∆ p = -mnv
Force = ∆p/t
F = mnv/1

forve = mnv .
