Question

Quizplus · Accepted Answer

The stone has no vertical velocity when it leaves your hand, so its vertical distance below the top of the cliff after one second is simply due to the acceleration due to gravity, which is 9.8 m/s^2. Therefore, the vertical distance below the top of the cliff after one second is 0.5 * 9.8 = 4.9 m, which is closest to 5 m.
