how much work is done by a 23 newton force on a box if the box moves 9 meters at an angle of 42 degrees from the direction of the force

Question

anonymous · Answer

Work done is defined by the scalar(also known as "dot") product of the relevant force and displacement vectors.
One way of calculating scalar products, which uses the information you have given, is multiplying the product of the magnitudes of the two vectors by the cosine of the angle between them.

Work = W= FS cos(theta)
you have,
force F, distance S and theta...
put in above equation you'll get the answer...
