Please solve subparts 4 and 5. Introduction: The pedal of a bicycle is attached to a crank arm that revolves when thepedal is pushed by a person’s foot. As the crank arm turns, it pulls a chain that isattached to the rear wheel of the bicycle, causing the bicycle to move forward. A particular bicycle has wheels that are 66 cm in diameter. The radius of the crank armis 18 cm. At its lowest point, the pedal is 16 cm above the ground. A person is pedalingthe bicycle such that the crank arm rotates once every second. Questions:4. Determine an equation that would model the foot’s position when the cyclist istraveling 5 km/h. Compare this equation to your equation from question 1 andexplain any differences.5.
