Answer:
(a) The time to complete 1 cycle and return is 16/3
(b) The minimum height is 30 inches and the maximum is 54 inches
Step-by-step explanation:
Given
Solving (a): Time to complete 1 cycle and return
This implies that we calculate the period. This is calculated using:
Where:
So, we have:
Solving (b): The maximum and the minimum height
To do this, we have:
Which means:
So, the minimum is:
And the maximum is:
Recall that the height is:
So, the maximum and the minimum of are:
and
Answer:
Step-by-step explanation:
Since and are equal, we can set them equal to each other:
Substitute to solve for :
20.2 * -2.5ft = -50.5ft
Hence, Winston reach -50.5 feet during his deepest dive.
