Answer to Question #335893 in Mechanics | Relativity for Melissa

Question

The mechanical power output of a cyclist moving at a constant speed of 5.90 m/s on a level road is 105 W.

 

By bending low over the handlebars, the cyclist reduces the air resistance to 18.0 N. If she maintains a power output of 105 W, what will her speed be?

Answer 1

$v_2=v_1\frac{F_1}{F_2}=1.01~\frac ms.$
