a car of mass 1500 kg traveling northward at 16m/s collides in an intersection with a 1700 kg car traveling at 12 m/s in a direction 30 degrees north of east. (a) assuming that the two cars become stuck, find the velocity of the wreck immediately after the collision. (b) calculate the average force on a 100kg passenger in the first car. duration of collision: change in t=50 ms
