Gwen releases a rock at rest from the top of a 39-m tower.If g = 9.8 m/s² and air resistance is negligible,what is the speed of the rock as it hits the ground?

Question

Quizplus · Accepted Answer

The speed of the rock can be calculated using the equation v = √(2gh), where g is the acceleration due to gravity (9.8 m/s²) and h is the height (39 m). Substituting the values, v = √(2 * 9.8 * 39) = 28 m/s.
