Sample Problem 9.04 Two-dimensional impulse, race carwall collision Race carwall collision. Figure 9-11a is an overhead view of the path taken by a race car driver as his car collides with the racetrack wall. Just before the collision, he is traveling at speed vi = 70 m/s along a straight line at 30 from the wall. Just after the collision, he is traveling at speed of: 50 m/s along a straight line at 10 from the wall. His mass m is 80 kg.
