Quizplus · Accepted Answer

The time taken for an object to fall a certain distance under gravity can be calculated using the formula $ t = \sqrt{\frac{2h}{g}} $, where $ h $ is the height (50 m) and $ g $ is the acceleration due to gravity (approximately 9.81 m/s²). Plugging in the values, $ t = \sqrt{\frac{2 \times 50}{9.81}} \approx 3.19 $ seconds.
