Question 100: Work, Energy and Power & Circular Motion

Question

Arrange the four graphs in descending order of total work done; where W1, W2, W3 and W4 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

W3 > W2 > W1 > W4

Answer

W3 > W2 > W4 > W1

Answer

W2 > W3 > W4 > W1

Answer

W2 > W3 > W1 > W4
