Calculate the Time Required for a Phone to Reach the Ground

The Scenario

A high schooler who lives on the "5th" floor of an apartment complex accidentally dropped his phone off the balcony. The balcony is located 18.75 meters above the ground. In this scenario, we need to calculate the time required for the phone to reach the ground.

The Calculation

To determine the time it takes for the phone to reach the ground, we can use the free falling formula:
T = √(L)/ g
Where: T = time in seconds L = height of the drop (in this case, 18.75 meters) g = acceleration due to gravity (9.8 m/s^2) Now, let's plug in the values and calculate:
T = √18.75/9.8 T = √1.91 T = 1.38 seconds

The Answer

The time required for the phone to reach the ground is 1.38 seconds.

Explanation

The time taken for an object to fall freely from a certain height can be calculated using the formula mentioned above. By substituting the values and performing the calculation, we find that it takes approximately 1.38 seconds for the phone to reach the ground.
