Answer:
A. W = 0joule
B.W = d * w * cos (90 -ø)
Explanation:
work done is force multiplied by distance since the distance covered by the dresser is zero so automatically work done in moving the dresser is 0 (zero)
B. The component of weight of box along the inclined plane = w * cos ( 90 - ø )
Where ø is the angle of inclination to the horizontal
W = weight of body due to gravity.
Since the distance traveled by box due to gravity = d
So therefore:
W = d * w * cos (90 -ø)
W = work done
N.b
