AA logarithm
BA derivative
CA square root
DA cube root
Answer & Solution
Correct answer: C. A square root
1. Square roots are motivated by a falling-object problem.
2. The problem is to find the seconds until a stone hits the land below.
3. To calculate that number of seconds we need to use a square root.
4. Falling-object formulas involve the square root of the height.
