Dear
The front-wheel drive car has a driving force of 1500 N per wheel. The air resistance is 370 N and the rolling resistance is 40 N per tire. What is the residual driving force?
The residual driving force can be calculated as follows:
Total driving force = Driving force per wheel x Total number of wheels
Total driving force = 1500 N/wheel x 2 wheels (since it is a front-wheel drive car)
Total driving force = 3000 N
Total resistance force = Air resistance + Rolling resistance per tire x Total number of tires
Total resistance force = 370 N + 40 N/tire x 4 tires (since each tire is subject to rolling resistance)
Total resistance force = 570 N
Residual driving force = Total driving force - Total resistance force
Residual driving force = 3000 N - 570 N
Residual driving force = 2430 N
Therefore, the residual driving force of the front-wheel drive car is 2430 N.
The tire have a driving force 3000N. The air resistance is 370N and the total rolling resistance is 160N.
What is the residual driving force?

To calculate the residual driving force, we need to subtract the forces of air resistance and rolling resistance from the driving force of the car.
The driving force per wheel is given as 1500 N, and since it's a front-wheel drive car, we assume that both front wheels contribute equally to the driving force. Therefore, the total driving force is 1500 N x 2 = 3000 N.
Next, we need to subtract the forces of air resistance and rolling resistance. The air resistance is given as 370 N, and the rolling resistance is 40 N per tire. Since there are two tires in the front, the total rolling resistance is 40 N x 2 = 80 N.
Now we can calculate the residual driving force:
Residual driving force = Total driving force - Air resistance - Rolling resistance
Residual driving force = 3000 N - 370 N - 80 N
Residual driving force = 2550 N
Therefore, the residual driving force of the front-wheel drive car is 2550 N.
