Question

This is a gordon rule question. Q#3 Suppose a cityblock is 100 meters long and quite steep.If you were to ride a bicycle up the hill along a zig-zag pathwhich is 200 meters long, the average force that you must exertis ----- the average force you would exert going straightup the hill . Select an answer from the list below and defend itusing your knowledge of the physics of Work and Energy. (a) 1/4 (b)1/3 (c)1/2 (d) equal to For the same hill along the zig-zag path, the energy youmust expend is ------- the energy that you would expend goingstraight up the hill. Select an answer from the list below anddefend it using your knowledge of Physics of Work and Energy. (a) 1/4 (b)1/3 (c)1/2 (d) equal to This is a gordon rule question.

Explanation / Answer

We have to answer the second part first.... Work=mgh (potential energy gained) Weather you travel 200 meters to get to the same height or 100m,the work you have to do is still the same. Also, W=F.S therefore,F1S1=F2S2 F1*100=F2*200 F2=0.5F1 answer (c)1/2 for the second part as stated above, answer (d)equal to
