Answer:
Kinetic energy is given by (1/2)*m*v^2. Momentum is given by m*v. We see that kinetic energy divided by momentum is equal to (1/2)*v. Because this ratio has dimensions of length/time, it is impossible for the kinetic energy to equal the momentum. You can get a numerical value of 1 by making v=2
