Michael is doing an experiment. He wants to drop a bowling ball and a stuffed bear out the window of a tall building. Under what conditions would they have the same acceleration?

If there was no air resistance

Explanation:

We know that free fall is a unique motion in which gravity only works on one object. Objects that are said to be free-falling do not experience a significant force of air resistance; They come under the sole effect of gravity. Under such conditions, all objects fall under the same acceleration, regardless of their mass.

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.

f=125n a=2.5m/s2
