Answer:

<u>Work Done = 27.66 Joules</u>

Step-by-step explanation:

The work done is:

W=F*d*Cos \theta

Where

F is the fore

d is the distance moved

\theta  is the angle

The force is "4"

The distance is the distance from (1,7) to (8,10)

The distance is the square root of change in y coordinates, squared and sum of change in x coordinates, squared. Hence, distance is:

\sqrt{(10-7)^2+(8-1)^2}\\=\sqrt{3^2+7^2}\\\sqrt{58}

The angle is gotten by the formula:

Cos\phi = \frac{Force in x direction}{Distance}\\Cos\phi = \frac{8-1}{\sqrt{58}}\\Cos\phi=\frac{7}{\sqrt{58}}\\\phi = Cos^{-1}\frac{7}{\sqrt{58}}\\\phi = 23.21

So, now:

\theta = 48 - 23.21 = 24.79

Work Done = F*d * Cos\theta = 4 * \sqrt{58} * Cos(24.79)

<u>Work Done = 27.66 Joules</u>
