Answer:
It takes 534.54 watts
Step-by-step explanation:
Given :
Mass of the book = 30kg
Distance = 10m
Time = 5.5 sec
To Find:
How much power did it take = ?
Solution:
Step 1: calculate the work done
Work done = 
where
m = mass
a = acceleration due to gravity
d = distance
Substituting the values,
Work done = 
=> 2940 Nm
Step 2: calculate the Power
We know that

Substituting the values,

Power = 534.54 watts
F(x) = y = -1/3x + 0
g(x) = y= -1/3x - 3
I don’t think that you have to include the y in the equations. It really depends on what your teacher wants. ;)
Hope this helps✨❤️
Merry Early Christmas!
