Question 2 (3 points) A rubber ball with a mass of 0.85 kg is dropped from a height of 2.00 m above the ground. It falls and hits the ground. After bouncing off the floor, the ball has a velocity of 2.50 m/s [up]. If the ball was in contact with the ground for 0.030 seconds, determine the average force applied by the floor on the ball during contact. Enter a number with three significant digits. Do not enter the direction of the force (only magnitude and units)
