Question

A body moves a distance of 10 kilometre under the action of force 10 newton if the work done is 25 joule find the angle which the force make with the direction of motion

Answer 1

Answer:

Where F = Force applied

s= distance of body

W= F s cos \alpha  

25 = 10 x 5 cos \alpha  

cos \alpha =\frac{1}{2}  

\alpha =60  

Thus, force makes angle of 60 degree with direction of motion
