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?

Answer :

Physics
What is the momentum of a 1.5 × 103 kilogram van that is moving at a velocity of 32 meters/second? A. 46.9 kilogram meters/second B. 4.7 × 103 kilogram meters/second C. 4.85 × 102 kilogram meters/second D. 4.85 × 104 kilogram meters/second
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
