AP Physics 1 Impulse Momentum Unit - Change of momentum in 2D

3. A golf ball (m = 0.047 kg) bounces of the floor as shown in the picture. What is the magnitude and direction of the impulse applied by the ball to the floor?
CORRECTION: missing mass - need to multiply by 0.047 kg for correct answer, it is NOT 45 roots of 3.
