Question

Imagine you are on the top of a mountain with four basketballs. The mass of the four basketballs are 100 kilograms, 200 kilograms, 300 kilograms, and 400 kilograms. If the basketballs rolled down the hill, which one would supply the greatest force at the bottom of the mountain (assume that their velocities were equal at the bottom of the mountain)?
A) 100 kilogram basketball
B) 200 kilogram basketball
C) 300 kilogram basketball
D) 400 kilogram basketball

Answer 1

\(F=ma\)
The mass seems to be variable here, yet if the velocities are all equal, this would imply their accelerations are equal as well. Hence in this scenario, we can conclude that the basketball with the greater mass will have the greatest force.

Answer 2

so 200?

Answer 3

Not 200; the one with the greatest mass.

Answer 4

400?

Answer 5

yes

Answer 6

ok
