A automobile travels at a speed of northward along a street, and a 7000N sports car travels at a speed of eastward along an intersecting street. (a) If neither driver brakes and the cars collide at the intersection and lock bumpers, what will the velocity of the cars be immediately after the collision? (b) What percentage of the initial kinetic energy will be lost in the collision?

been there, done that
