Problem: A 6 kg steel ball strikes a wall with a speed of 11.2 m/s at an angle of 50.5° with the normal to the wall. It bounces off with the same speed and angle, as shown in the figure. If the ball is in contact with the wall for 0.219 s, what is the magnitude of the average force exerted on the ball by the wall?1. 366.422. 239.5713. 170.7364. 390.365. 1456.096. 136.0937. 226.8328. 287.429. 335.95510. 714.377
