conserve momentum. Since the masses are equal, just work with velocities.
0 + 15<1,0> = v1<cos4°,-sin4°> + v2<cos18°,sin18°>
now solve for v1 and v2
Two equal mass hockey pucks collide in a perfectly elastic collision. The first
puck is stationary, and the second puck collides with the first while
travelling 15 m/s [E]. The first puck travels in the direction of [E4°S], while the second puck travels with an unknown velocity, but with a direction of [E18°N]. Determine the final velocities of both pucks.
