A rifle with a weight of 30 N fires a 3.0 g bullet with a speed of 250 m/s.
(a) Find the recoil speed of the rifle.
(b) If a 675 N man holds the rifle firmly against his shoulder, find the recoil speed of the man and rifle.
I got .245 m/s for the first one but I keep getting the second wrong, how do I do it?
retards do your own work
