A car (of mass 1500 kg) and a small truck (of mass 2000 kg) collide suddenly at right angles at an icy intersection.

The car was originally traveling eastward at 20.0 m/s and the truck was traveling northward at 20.0 m/s just before the collision took place. What is the speed of the combined wreck just after the collision if the vehicles become enmeshed?

A) 4.8 10-14 N
B) 1.9 10-15 N
C) 5 10-20 N
D) 0 N
E) 2.2 10-24 N
