(1) Determine the amount of work in joules that a car that is driven 150 km must do, if an average force of 500 N is applied to overcome friction? (IT)​

Workdone = 75000000 Joules or 75 Megajoule.

Explanation:

Given the following data;

Distance = 150km to meters = 150 * 10³ = 150000 meters

Force = 500 Newton

To find the workdone;

Workdone = force * distance

Substituting into the equation, we have;

Workdone = 150000 * 500

Workdone = 75000000 Joules or 75 Megajoule.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
