When a bicycle rider is traveling at a speed of V = 24 mph, the power P

Question:

When a bicycle rider is traveling at a speed of V = 24 mph, the power P she needs to supply is given by P = FV, where F = 5 lbf is the force necessary to overcome aerodynamic drag. Apply the grid method to calculate:

a. Power in watts.

b. Energy in food calories to ride for 1 hour.
