Question

Mass of rifle is 6kg, mass of bullet is 0.01kg travelling at 350m/s what is the velocity

Answer 1

Use the conservation of momentum formula: m1v + m2v = m1v + m2v

(6kg)(0m/s) + (0.01kg)(0m/s) = (6kg)v + (0.01kg)(350m/s)

0  = (6kg)v + (0.01kg)(350m/s)

-(6kg)v = (0.01kg)(350m/s)

v = ((0.01kg)(350m/s)) / -6kg

v = -0.58 m/s to the other direction
