Average speed=total distance travelled/time
Answer:
30.46 kgm/s
Explanation:
According to conservation law of momentum, the magnitude of the impulse J that the ground gave the ball equals to the change in momentum of the ball before and after it hits the ground.
Before the hit, the ball velocity is 6m/s, so its momentum is 6 * 2.89 = 17.34 kgm/s
After the hit, the ball velocity is -4.54 m/s in the opposite direction, so its momentum is 2.89*(-4.54) = -13.12 kgm/s
So the change of momentum, and also the impulse is
17.34 - (-13.12) = 30.46 kgm/s
