A bicycle and rider have a combined mass of 114.0 kg. How many calories of heat are generated in the brakes when the bicycle comes to a stop from a speed of 32.2 km/h? kcal
Homework Answers
Here,
initial speed , u = 32.2 km/hr
u = 32.2 * 1000/3600 m/s = 8.94 m/s
mass = 114 Kg
heat generated = loss in kinetic energy
heat generated = 0.50 * 114 * 8.94^2
heat generated = 4560 J
heat generated = 4560/4186 Kcal
heat generated = 1.09 Kcal
the heat generated is 1.09 Kcal

A mountain bicycle with 26 inch (0.660 m) diameter tires (mass of 15 kg, mass of each tire is 1 kg) has a rider (mass of 100 kg). The rider travels along a flat road with a speed of 10.0 m/s. The road then goes uphill with a slope of 1.4 degrees. If the rider is not pedaling and you ignore friction and air drag, how far up the hill does the rider on the bike go?

A woman rides a bicycle down a hill with a 15% slope (rise/run). The combined mass of the bicycle plus woman is 50 kg. She is riding into a 20-km-per hour wind. The only forces acting on the woman are drag force and weight. If the woman and bicycle together have a projected area of 1.0 m2, and the coefficient of drag is 1.1, how fast is the bicycle going relative to the ground? The density of air is 1.23...
