The total mass of the bk wters 25% Part (a) Select the correct free body diagram. 25% Part (b) Calculate how much work Wrin J the farmer does on the bucket of water (via the rope) to raise it to ground level. 25% Part (c) Calculate how much work water as the farmer lifts it up the well. in J gravity does on the bucket filled with 25% Part (d) Calculate the net work line in J done on the bucket of water by the two forces Fi and F All content ©2017Exper TA, Luc

Explanation / Answer

b)

Work done by farmer

W_f = (F * d) = 55 x 16 = 880 Joules.
c)

Work done by gravity =(m_w +m_b)*g*h = (36.26 x 16) = 580.16 Joules.
d)

Net work done = (880 - 580.16  ) = 299.84 Joules.

W_net = 300 Joules is the net work done on the bucket of water by two forces
