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 di
erica [24]

Hello!

The answer is:

Luke did a work of 308N.m or 308 Joules.

<h2>Why?</h2>

When a force is applied on a object making it to move covering a distance we call it "work". 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 or 308 Jouls.

Have a nice day!

What is the location of F on the decimal number line below?<br> Write your answer as a decimal
Masja [62]

Answer:

6.45

Step-by-step explanation:

Every part is 0.01 bigger or smaller

You can find it out by subtraction and then division

6.5 - 6.4 = 0.1

0.1 : 10 = 0.01

There are 10 parts that's why you divide it by 10.

If there will be 2 parts you will divide by 2
