Question

A bicyclist is stopped at the entrance to a valley, as sketched below: Where would the bicyclist have the highest potential energy? (choose one) Where would the bicyclist have the lowest potential energy? (choose one) Where would the bicyclist have the highest kinetic energy? Where would the bicyclist have the highest speed? Would the bicyclist's kinetic energy be higher at B or C? (choose (choose one) Would the bicyclist's potential energy be higher at B or C? Would the bicyclist's total energy be higher at B or C Suppose the bicyclist lets off the brakes and coasts down into the resistance to slow him down, what is the farthest point the bicydist could reach without pedaling?

Explanation / Answer

According to the given problem,

a) Ans: Point F has the highest height.

b) Ans: Point B has the lowest Height.

c) Ans: Point B as the height change is maximum so K.E max.

d) Ans: Point B as the height change is maximum so K.E max and max velocity.

e) Ans: Point B as the height change of A-B is maximum than B-C

f) Ans: Point C as B is the lowest point in the valley.

g) Ans:  Point B as the height change is maximum so K.E max and height change from B-C is comparitivly less so less total energy than B.

h) Ans: Point E [Mostly] as the Height is same and Using energy conversion [no frcition ans air resitance].

I hope you understood and you got the problem correct, If yes rate me! or else fell free to comment.
