SUMMARY
The discussion centers on a physics problem involving a stone thrown horizontally from a cliff at a speed of 16.0 m/s, with the cliff height being 62.0 m. The correct approach to determine the time of impact and the angle of impact is clarified through the use of kinematic equations. The time of fall is calculated using the equation s = ut + ½at², where the initial vertical speed (u) is 0 m/s and acceleration (a) is -9.8 m/s². The final calculation yields a time of approximately 3.56 seconds for the stone to strike the beach below.
