Two objects have unequal masses, m1 > m2. If their kinetic energies are equal, which has the greater momentum? This is the way I approached this problem. I know that, Momentum = mass*velocity K = 1/2mv^2 So, I solved for v since it is the only unknown in these two equations. k = 1/2mv^2 2k/m = v^2 √2k/m = v And plugged it into the first equation for momentum. Momentum = m√2k/m = √m^2*√2k/m = √m^2 2k/m = √2k m However, since 2k is a constant between the two massess I removed them from the equation giving me Momentum = √m Since m1>m2 I thought it was safe to say that the momentum of object 1 is greater than the momentum of object 2; however, I was wrong. According to the answer the momentum of m2 is greater than m1 so I'm just wonder, why? Is my math wrong, am I not suppose to join these two equation? If somebody can help I would greatly appreciate it. Thank you for taking the time to review my question.
