2. Two hockey players are skating on the ice and collide with an "embrace" (stick together), the ice rink is in the \( x y \)-plane ( \( x y \) is East-North, with the goals at the East and West ends). Just before the collision the \( 111 \mathrm{~kg} \) defensive player is skating backwards with a velocity of \( -1.50 \hat{\imath} \mathrm{m} / \mathrm{s} \), and the \( 93 \mathrm{~kg} \) right wing player is skating forwards towards the defensive player at \( 5.90 \mathrm{~m} / \mathrm{s} \) at a polar angle of \( 153.0^{\circ} \).
d. Calculate the \( \% \) of kinetic energy conserved in the collision \( \left(K_{f} / K_{i} \times 100 \%\right) \).
