Tobias dropped a tennis ball from a height of 60 meters. The time in seconds it takes for that ball to fall 60 feet is \(0.25(\sqrt{60})\). Find three sets of approximations for the amount of time it will take. Then determine how long it will take for the ball to hit the ground.

The number of swings back and forth of a pendulum of length L in inches each minute is \(\cfrac{375}{\sqrt{\text{L}}}\). About how many swings will a 40-inch pendulum make each minute?
