Find the work W done by a force of 3 pounds acting in the di

Find the work W done by a force of 3 pounds acting in the direction 60 degree to the horizontal in moving an object 4 feet from (0, 0) to (4, 0). W = foot-pounds (Round to the nearest whole number as needed.)

Solution

Work Done = Force x Distance x cos theta

Force = 3 pounds

Distance = 4 feet

Theta = 60 degrees

So, Work Done = 3 x 4 x cos 60 = 6 (Answer)
