A rubber ball and a steel ball are dropped from the same height onto a concrete floor. They have the same mass, and lets assume that they both rebound to the same height after hitting the ground. How would the average forces experienced by the balls compare. Group of answer choices The steel ball would experience the greater average force The average forces would be the same The rubber ball would experience the greater average force

The average forces would be the same

Explanation:

Both have the same velocity on impact as they fell from the same height.

Both have the same velocity after the bounce because they reach the same height.

Both have the same mass

Both will thus experience the same impulse because both have the same change in momentum.

Therefore both experience the same average force.

Explanation:

What you forgot to include is the mass of the earth, which is 5.98 × 10²⁴ kg. NOW we can do the problem:

where m1 and m2 are the masses of the objects experiencing this force of gravity, F. G is the universal gravitational constant. Filling in:

We are going to rearrange and solve for r before we do any math on this thing:

and when we plug all that mess into our calculators we will do it just like that and then round to 3 significant digits at the very end.

Doing all of that gives us that

r = 3.83 × 10⁸ m
