A 12000N car travels at a speed of40 km/h northward along a street, and an 8500 N sports car travels at a speed of 62 km/h eastward along an intersecting street.
a. If neither driver brakes and the cars collide at the intersection and lock bumpers, find what will the magnitude of the velocity of the cars be immediately after the collision?
b. Find the direction of the velocity of the cars be immediately after the collision?
c. Find percentage of the initial kinetic energy will be lost in the collision?
