At time t = 0, two skaters of different masses (M1 = 50 kg and M2 = 70 kg) are at rest on ice. Skater 1 pushes away skater 2 for 2 seconds with a force of 100 N. Assume, there is no friction between the ice and the skaters.
After 2 seconds, which statement correctly describes the relationship between the kinetic energies K1 of skater 1 and K2 of skater 2?
a. K1 > K2
b. K1 = K2
c. K1 < K2
