Answer:
1. Fk = 24N, Fs = 60N
2. Fk = 60N, Fs = 84N
For 3, is it saying the car weighs 9000N? In that case, you’d convert Newtons to kg. then you’d find normal force by using Fn = mg (because Fn = mass x gravity) finally since you’ve found Fn, use Fk=ukFn and Fs=usFn to find kinetic and static friction.
Explanation: My work is in the picture below. Hope this helps!

<h3>Area of shaded region is 21.5 square centimeter</h3>
<em><u>Solution:</u></em>
The area of the shaded region is equal to the area of the square minus the area of the circle
<em><u> Find the area of the square</u></em>
Where, "a" is the length of each side
From given figure in question,
a = 10 cm
<em><u>Find the area of circle </u></em>
The area of the circle is given as:
Where, "r" is the radius of circle
Diameter = 10 cm
Thus,
<em><u>Find the area of the shaded region</u></em>
Area of shaded Region = Area of Square - Area of Circle
Area of shaded Region = 100 - 78.5 = 21.5
Thus area of shaded region is 21.5 square centimeter
