Question

A bullet of mass 20 grams is fired horizontally with a velocity of 300 M per second from a pistol of mass 4 kg find the recoil pistol​

Answer 1

m1 = 20g

m2 = 4 kg

v1 = 300m

v2 = ?

u1 = 0

u2 =

m1u1 + m2u2 = m1v1 + m2v2

0.002 x 0 + 4 x 0 = 0.002 x 300 +4 x v2

0 = 0.6 + 4v2

-0.6/4 = v2

-0.15 m/s = v
