A 1325 kg car moving north at 20.0 m/s hits a 2170 kg truck moving east at 15.0 m/s. After the collision, the vehicles stick together. The velocity of the wreckage after the collision is: Select one: O a. 12.0 m/s [51°] O b. 12.0 m/s [51° E of N] O c. 4.20 x 104 m/s [51°] O d. 4.20 × 10% m/s [51° N of E] And calculate the magnitude of momentum of the truck before the collision
