Before a collision, the x-momentum of an object is 8.0 * 103 kilogram meters/second, and its y-momentum is 1.2 * 104 kilogram meters/second. What is the magnitude of its total momentum after the collision?

Take (8.0x10^3) ^2 + (1.2x10^4) ^2 = c^2 and solve for c

64000000 + 144000000 = c^2

208000000 = c^2

c = 14422 kg * m/s = 1.4x10^4 kg * m/s
