A bungee jumper attains a speed of 30 m/s just as the bungee cord begins to stretch.If the period of stretch is 2 s,the magnitude of the jumper's average deceleration is about

Question

Quizplus · Accepted Answer

The average deceleration can be calculated using the formula: deceleration = change in velocity / time. The change in velocity is 30 m/s (from 30 m/s to 0 m/s), and the time is 2 s. Thus, deceleration = 30 m/s / 2 s = 15 m/s². Since g ≈ 9.8 m/s², 15 m/s² is approximately 1.5 g.
