Calculate the amount of work done by the force in moving the object through a distance of 9 m if an object is horizontally dragged across the surface by a 130 N force acting parallel to the surface.
a. 1170 J
b. .070 J
c. 14 J
d. 507 J
The work done by a force can be calculated using the formula:
Work = Force x Distance x cos(angle)
In this case, the force is acting parallel to the surface, so the angle between the force and the direction of motion is 0 degrees. Therefore, the cosine of the angle is 1.
Work = 130 N x 9 m x cos(0)
= 1170 J
So, the amount of work done by the force in moving the object through a distance of 9 m is 1170 J, which corresponds to option a)
