SUMMARY
The discussion centers on calculating the time it takes for Bob to reach the ocean after running off a cliff at a horizontal velocity of 4.2 m/s from a height of 110 meters. Using the equation Y = Vo + 1/2at², where Y represents height, Vo is the initial vertical velocity (0 m/s), and a is the acceleration due to gravity (-9.8 m/s²), the solution yields a time of approximately 4.74 seconds for Bob to hit the water. The calculation is confirmed to be accurate, emphasizing the importance of understanding projectile motion in physics.
