A 17000 N automobile travels at a speed of 50 km/h northward along a street, and a 7500 N sports car travels at a speed of 65 km/h eastward along an intersecting street.
a) If neither driver brakes and the cars collide at the intersection and lock bumpers, what will the magnitude of the velocity of the cars be immediately after the collision? (wants an answer in km/h, NOT m/s)
b) What will the direction of the velocity of the cars be immediately after the collision? (degrees north of east)
