a) Find the recoil speed of the rifle.
b) if a700N man holds the rifle firmly against his shoulder, find the recoil speed of man and rifle.

Answer 1

m = 30/9.81

a) (30/9.81)v = .005 * 300

b) (730/9.81)v = .005 * 300

Answer 2

0.5 m/s

Answer 3

1(30/9.81)v = .005 * 300
2.(730/9.81)0+0.005*300=(730/9.81+0.005)v
v=0.020m/s
