Question

a force of 50 Newton acts on a body and moves it a distance of 4 m on a horizontal surface calculate the work done if the direction of force is at an angle of 60 degree to horizontal surface​

Answer 1

Force, F = 50 N,
Displacement, s = 4 m
Direction of Force is at an angle of 60o
Formula used:
Work done
Putting the values in above equation we get:-
= 50 × 4 × Cos 60°
= 50× 4 × 1/2
= 100 J
