A ball is rolling across the floor. Why does the ball come to a stop? The force of gravity stopped it.

The force of friction stopped it.

The normal force stopped it.

It had too much mass.

Explanation:

the notmal focrce stopped it.

It's C the friction stopped it

Explanation:

Gravity has a little effect on it. However the main force stopping the ball rolling is the friction force of the floor. The ball will stop rolling when the velocity of the ball is the same as the velocity of friction force.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
