Two hockey pucks are initially at rest on a horizontal plane of frictionless ice. Puck A has twice the mass of puck B. Suppose we apply the same constant force on each puck until each puck has crossed a finish line 1 m away from its starting point. How do the puck’s kinetic energies compare when each crosses the finish line?
A. KA = 4KB B. KA = 2KB C. KA = KB D. KB = 2KA E. KB = 4KA F. Some other relationship (specify)
