Question 109: Work, Energy and Power & Circular Motion

Question

Arrange the four graphs in descending order of total work done; where W
1
, W
2
, W
3
and W
4
are the work done corresponding to figure a, b, c and d respectively.

Accepted Answer

W
a
= 0, W
b
= +ve, W
c
= +ve > W
b
, W
d
= $$-$$ve
$$\Rightarrow$$ W
c
> W
b
> W
a
> W
d
$$\Rightarrow$$ W
3
> W
2
> W
1
> W
4

Answer

W
3
> W
2
> W
1
> W
4

Answer

W
3
> W
2
> W
4
> W
1

Answer

W
2
> W
3
> W
4
> W
1

Answer

W
