Answer:
A) When the angle between the Force (F) and Displacement (x) is 0°, because, Work done (W) is directly proportional to the Cosine of the Angle between the Force applied and the resultant displacement of the subject.
W = F•x cos ∅
If ∅ = 0°,
W = F•x ===> Maximum Work Done.
If ∅ = 45°,
W = F•x/√2
If ∅ = 90°,
W = 0
If ∅ = 180°,
W = –F•x ===> Minimum Work Done.
(B)Option b is your answer..........
Since the direction of the force and the direction of the path is perpendicular, the person is not doing any physical work.
The tangent looks good.
The curve is a bit crooked, at the 0.9 and 1.
But overall, cool graph.
