each wheel of a bicycle is of radius is 1.1 ft. if the wheels are making 4 revoultions per second how fast is the bicycle moving
C = 2 pi r, so
the circumference of the tire is 2 pi * 1.1 = 2.2 pi
2.2 pi ft/rev * 4 rev/s = 8.8 pi ft/s
To calculate the speed of the bicycle, we need to determine the distance covered by the bicycle in one second.
Given that each wheel has a radius of 1.1 ft, the circumference of each wheel can be calculated using the formula:
Circumference = 2 * π * radius
Circumference = 2 * 3.14 * 1.1 = 6.88 ft (approximately)
Since each wheel makes 4 revolutions per second, the distance covered by the bicycle in one second is simply 4 times the circumference of the wheel.
Distance covered by the bicycle in one second = 4 * 6.88 = 27.52 ft
Therefore, the bicycle is moving at a speed of 27.52 ft/second.
