**Answer:** c. 25%
---
**Question 7:** Describe why a bowling ball and a baseball dropped off of a cliff at the same time would land at different times, but they would land at the same time in a vacuum.
**Your answer:** In air, the bowling ball, being heavier and having a larger surface area, would be subject to more air resistance than the lighter baseball, causing it to fall slower. However, in a vacuum, there is no air resistance, so both the bowling ball and the baseball would experience the same gravitational acceleration and would land at the same time.
