A function assigns the values. The time it will take for the rock to reach the ground from a height of 125 feet is 2.795 seconds.
A function assigns the value of each element of one set to the other specific element of another set.
Given that the formula t=√h/4 represents the time t in seconds that it takes an object to fall from a height of h feet.
Now, in order to calculate the time, it will take for the rock to fall from the height of 125 feet, simply substitute the height of the rock from which it is dropped in the formula given.
Therefore, the time it will take for the rock to reach the ground from a height of 125 feet is,
t = √h / 4
t = (√125) / 4
t = (5√5) / 4
t = 2.795 seconds
Hence, the time it will take for the rock to reach the ground from a height of 125 feet is 2.795 seconds.
