The current that produces maximum power
First, we represent the function in standard form
Open bracket
The maximum value of c is:
Where:
By comparison:
So, we have:
The total is $36.3975. you will probably have to round that :)
The displacement between t = 0 and t = 3 is 45 meters, so the correct option is d.
<h3>
How to find the displacement?</h3>
The displacement is defined as the difference between the final position and the initial position.
The initial position is what we get when we evaluate in t = 0.
s = 0^3 -18*0^2+60*0 = 0
The initial position is 0 meters.
The initial position is what we get when we evaluate in t = 3.
s = 3^3 -18*3^2+60*3 = 45
The final position is 45 meters.
Then the displacement is:
D = 45m - 0m = 45m
The correct option is d.

-5t+5t+2+8-8
-5t+5t=0 or t
2+8-8=2
t+2 is the final answer
