Question

If Luke pushes his sister in a wagon down the driveway that is 14 meters long and it takes 22 Newtons of force, how much work did he do? 20 points !!

Answer 1

Hello!

The answer is:

Luke did a work of 308N.m

Why?

The work appears when a force is applied on a object making it to move covering a distance. The movement caused by the force, will follow the same direction that the force.

We can calculate the work done by using the following equation:

`Work=Force*distance*Cos(\alpha)`

Where,

Work is the transferred energy.

Force, is the force applied to the object.

Distance, is the distance covered due to the applied force.

α, is the angle at the work is done.

We are given the following information to calculate the work done:

`Force=22N\\Distance=14m`

So, substituting the given information into the equation to calculate work, we have:

`Work=Force*distance`

`Work=22N*14m=308N.m`

Hence, we have that Luke did a work of 308N.m

Have a nice day!

Answer 2

308 joules

Explanation:

The formula for work is

Work = force * distance

The unit for work is newton-meters, or joules. So the force needs to be in newtons and distance in meters.

The force given is 22 Newtons and distance given is 14 meters, plugging it into the formula, we get:

Work = 22 * 14 = 308 Newton-meter, or joules
