Calculate the energy and power required for a student to bike their way to college from home. The student bikes from home for 0.8 miles on flat terrain before stopping at a stop sign, then bikes for 0.5 miles before stopping at another stop sign, and then finally reaches the college after biking for 0.4 miles after the second stop sign. Combined Mass of the student and the bike - 175 lbs Maximum speed - 4.9 mph Acceleration and Deceleration - 2.95 ft/s2 CRR = 0.004 A = 5.5 ft2 Cd = 1.1 rho= 1.3 kg/m3
To solve the problem, we need to analyze all forces acting on a bicycle individually. In question, student bikes on flat terrain so gravity force doesn't affect the road load. This is the case of uniform acceleration and deceleration so need to calculate average velocity to find Air resistance.
Kindly check the attached images below to see the step by step explanation to the question above.
