if two racer cyclists are on a hill and A cyclist is up higher on a hill than B cyclist why does the A cyclist have less kinetic energy than cyclist B?
A.There is less friction between the tire and the road at position A than at position B
B. There is more friction between the tire and the road at position A than at position B
C. The cyclist has less speed at position A than position B
D.The cyclist has greater speed at position A than position B
(the answer is obviously not D)

I did the test and it said C was right
the question is lacking in detail ...
the assumption is apparently that the two cyclists had equal
energies at the bottom of the hill
as they climb the hill , kinetic energy (motion) is converted
to potential energy (position in a gravitational field)
the higher cyclist has greater potential energy , but less kinetic energy

sorry I couldn't find the image, the cyclist are going down the hill already
could someone please help me !!!!
