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!

Please solve the question and chose from the provided answer options.
Nezavi [6.7K]

Answer:

Option A is correct.

Step-by-step explanation:

We are given the expression:

w(x) = (x+125)^1/3

We need to find w(50)

Putting x = 50 in the above equation

w(x) = (x+125)^1/3

w(50) = (50+125)^1/3

w(50) = (175)61/3

w(50) = 5.59

w(50) = 5.6

So, Option A is correct
