1. The problem statement, all variables and given/known data There's actually 2 problems that I'm totally stuck on: A. Bullets from two revolvers are fired with the same velocity. The bullet from gun #1 is twice as heavy as the bullet from gun #2. Gun #1 weights three times as much as gun #2. The ratio of momentum imparted to gun #1 to that imparted to gun #2 is ? B. Two bodies, A and B, have equal kinetic energies. The mass of A is nine times that of B. The ratio of the momentum of A to that of B is ? 2. Relevant equations KE = 1/2*m*v2 P = m*v 3. The attempt at a solution A. I figured if the gun weighed 3 times gun #2, and the bullet weighed twice as heavy, the answer would be 6:1? B. And for A: 1/2*9m*v2 So for B: 1/2*m*(3v)2 So for momentum: A = 9m*v B = m*3v So the ratio is: 3:1? I'm pretty sure Problem A is wrong, just not sure what to do. However, I think I did Problem B correctly, but I'm not positive.
