Question

Al revolver of mass 500 gram fires a bullet of mass 10 gram with a speed of
$10 {ms}^{ - 1}$
find (1). the momentum of the bullet
(2). initial momemtum of the revolver and Bullet as a system and
(3). recoil velocity of the revolver



Please help me guyz

Answer 1

1) momentum = mass * velocity = 0.01*10 = 0.1 kgm/s
2) initial momentum of the bullet and gun as whole = mu = (0.5+0.01)*10 = 5.1 kgm/s
3) recoil velocity = -10m/s
