A bicyclist on an old bike (combined mass: 94 kg) is rolling
down (no pedaling or braking) a hill of height 129 m. Over the
course of the 309 meters of downhill road, she encounters a
constant friction force of 342 Newton. If her speed at the top of
the hill is 5 m/s, what is her speed at the bottom of the
hill?
