A force of 40 Newton acts on a object at an angle of 45 degree with horizontal as a result the object is displaced horizontally through a distance of 14 metres calculate the work done by the force on an object

Expert Answer:

F = 40 N
θ = 45 degree
s = 14 m 
 
W = Fs cosθ
W = 40 × 14 cos 45º
W = 40 × 14 × 0.707= 395.92 J
 
Thus, work done on an object to move it by a distance of 14 m is 396 J (approax.)
