Question

If you pushed a car 25 m and did 60 kJ of work, how much force did you use?

Answer 1

Answer:

Work = F_net * d

60 kJ = F_net * 25 m

60,000 J = F_net * 25 m

F_net = 60,000 J / 25 m

F_net = 2,400 N

The net force used was 2,400 N.

Answer 2

Force = 2,400 N

Given:

pushed a car 25 m and did 60 kJ of work.

To Find:
how much force did you use?

Solution:
To calculate the force used to push the car, we need to use the formula:

Work = Force x Distance

Where Work is measured in joules (J), Force is measured in newtons (N), and Distance is measured in meters (m).

We have been given the values of Work and Distance, so we can rearrange the formula to solve for Force:

Force = Work / Distance

Plugging in the given values, we get:

Force = 60 kJ / 25 m

First, we need to convert the unit of work from kilojoules (kJ) to joules (J):

60 kJ = 60,000 J

Now we can substitute this value into the formula:

Force = 60,000 J / 25 m

Simplifying this expression, we get:

Force = 2,400 N

Therefore, you used a force of 2,400 newtons to push the car 25 meters while doing 60 kJ of work
