Question
A basketball player jumped straight up to grab a rebound. If she was in the air for 0.80 second, how high did she jump?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Time in air is total time up and down. Time to reach max height = 0.40 s. Height h = ½gt² = ½ × 9.8 × (0.4)² = 4.9 × 0.16 = 0.784 m ≈ 0.78 m.
Hint
For symmetric flight, time up = total time/2.
