A 10 g bullet accelerates to 400 m/s after being fired from a gun with a mass of 2.0 kg.
(i) What is the momentum of the bullet?
(ii) What is the momentum of the gun?
(iii) What is the velocity of the recoiling gun?
Answers: 1
![P=0.01*400\\P=4[kg*m/s]](/tpl/images/1011/1078/12041.png)
![v_{recoil}=P/m\\v_{recoil}= 4/2\\v_{recoil}=2[m/s]](/tpl/images/1011/1078/d8ea7.png)
