3. Overhead view of the path of race car and wall collision is shown below. Just before the collision, car travels
at speed 70m/s along a straight line at 30 degrees from the wall. Just after the collision, it travels at speed 50
m/s along a straight line at 10 degrees from the wall. If the total mass is 80kg, what will be the impulse on the
car due to collision?
