The grade resistance F of a car traveling up or down a hill is modeled by the equation F=w sin, where W is the weight of the car and theta is the angle of the hills grade. What is the grade resistence

The correct question is in the attachment

Step-by-step explanation

Grade resistance is the simplest form of resistance. It is the gravitational force acting on the vehicle.

The grade resistance is given as.

Rg=WG

W= Vehicle Weight

G= Grade (length/length)

The grade resistance is modeled as

F=WSinθ

Since the car is moving downhill at an angle of 5°

Then, θ=-5° for downhill θ is negative

Give that the weight of the car is 2100lb

Then, grade is

F=WSinθ

F=2100Sin(-5)

F=-183.03lb

Approximately

F=-183lb
