Calculate the average force F acting on car

N In summary, the average force acting on the car in the given process is 93.65N. The work done by the car is 5.9x10^5 J while traveling a distance of 6.3 km at constant speed, and using the equation W=F\Deltax, the average force can be calculated to be 3717 N, but this is incorrect as the calculator was used instead of solving it manually. The correct average force is 93.65N.

Calculate the average force F acting on car

Homework Statement



A car does the work Wcar=5.9x105 J in traveling a distance x=6.3 km (6300 m) at constant speed.

Calculate the average force F (from all sources) acting on the car in this process.

Homework Equations



Work = Force x Distance = F [tex]\Delta[/tex]x

The Attempt at a Solution



Since W=F[tex]\Delta[/tex]x
W=F/x

so F=5.9x10^5 J / 6300 m = 3717 N

Which is wrong. Not sure what else i could do. I'm not given any information other than supplied.

It's wrong because i was being lazy and used the calc on the computer...

Anyway answer is 93.65
 

1. What is the formula for calculating average force on a car?

The formula for calculating average force on a car is F = m * a, where F is the force, m is the mass of the car, and a is the acceleration.

2. How do you determine the mass of a car for this calculation?

The mass of a car can be determined by using a scale or by looking up the manufacturer's specifications for the specific car model.

3. What is the unit of measurement for force in this calculation?

The unit of measurement for force in this calculation is Newtons (N).

4. Can the average force on a car vary during a trip?

Yes, the average force on a car can vary during a trip depending on factors such as changes in speed, road conditions, and forces from other objects (e.g. wind).

5. How can knowing the average force on a car be useful?

Knowing the average force on a car can be useful for understanding the performance and efficiency of the car, as well as for making adjustments to improve its performance and safety.
