Question

5. A man whose mental health can be seriously questioned is trying to bicycle through an ellipse-shaped loop. The total mass of the man and his bicycle is 85 kg, and the center of mass is 1.2 m from the ground. What is the minimum speed he has to have at A in order to be able to perform this stunt without embarrassing (and potentially lethal) results? Neglect friction, air resistance, and the size of wheels. +f = 1 3m

Step 1

The gravitational potential energy is given by the equation: PE = mgh where m is the total mass of the man and his bicycle (85 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the height of the center of mass from the ground (1.2 m). PE = (85 Show more…
