Consider a race car colliding with the track wall. Just before the collision, the car (with the driver) is traveling at a speed vo=9.0 m/s along the straight line with an angle of θ1= 31o from the wall. After the collision, the car is travelling at a speed of v=46 m/s at an angle of θ2= −12o from the wall. The total mass of the car and its driver is 1542 kg. Calculate the direction (in degrees) of the impulse. Measure the angle from the +x-axis counterclockwise.   Give formula first then solve.
