$458\mathrm{.}275$

Two ice skaters push off against one another starting from a stationary position. The $45\mathrm{.}0-kg$ skater acquires a speed of $0\mathrm{.}375\frac{m}{s}.$ What speed does the $60\mathrm{.}0-kg$ skater acquire? Assume that any other unbalanced forces during the collision are negligible.
