Unformatted text preview: b). The hill the biker is climbing is 100m high and 1000m long (hypotenuse). If her mass is, m=50kg, and potential energy is P e = m g h , how much energy will she need to get up the hill? (let g=10m/s 2 ) c). If the bicycle has a wheel diameter of d=2 =π , how many rotations will the wheel require to climb the slope? How much energy is needed for each rotation? d). What should the gear ratio be to be sure she makes it up the hill? Hint: how many pedal rotations are required to give the bike enough energy to rotate the wheel once? 4...
