Q17. As shown in the image below, the 0.5-kg ball strikes the rough ground and rebounds. The directions of its velocities before and after the strike are shown. If the speeds are vị = 21 m/s and v2 = 13 m/s, determine the magnitude of the impulse (in N-s) the ground exerts on the ball. Assume that the ball does not slip when it strikes the ground, and neglect the size of the ball and the impulse produced by the weight of the ball. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point.
