Two identical black holes collide head-on. Each of them has a
mass equivalent to 32 solar masses. (The sun has a mass of about
2×10^30 kg.) As the black holes collide, they merge, forming a
single, larger black hole and additional gravitational waves that
carry momentum out of the system. Before the collision, one black
hole is moving with a speed of 52 km/s, while the other one is
moving at 66 km/s. After the collision the larger black hole moves
with speed 5 km/s. How much momentum was carried away by
gravitational waves?
