SUMMARY
The discussion focuses on calculating the change in momentum of a ball with a mass of 4.7 kg, initially moving at 1.9 m/s in the x-direction and bouncing back with the same speed in the -x-direction. The initial momentum is calculated as 8.93 kg·m/s, while the final momentum is -8.93 kg·m/s. The change in momentum (Δp) is determined to be -2P, resulting in a total change of momentum of -17.86 kg·m/s, indicating a direction towards -x.
