A force of 4 pound acts in the direction of 48degree to the horizontal. The force moves an object along a straight line from the point (1,7) to the point (8,10), with distance measured in feet. What is the work done?

Work Done = 27.66 Joules

Step-by-step explanation:

The work done is:

Where

F is the fore

d is the distance moved

 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:

The angle is gotten by the formula:

So, now:

Work Done =

Work Done = 27.66 Joules

step-by-step explanation:

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
