Conversions and Calculations in Linear Motion

The video tutorial explains how to calculate the angular and linear velocities of a bicycle wheel with a diameter of 16 inches, rotating at 165 revolutions per minute. It covers the conversion of these velocities into different units, including miles per hour. The tutorial provides step-by-step calculations, starting with determining the angular velocity in radians per minute, followed by the linear velocity in inches per minute, and finally converting the speed to miles per hour using unit fractions.

What is the approximate angular speed of the wheel in radians per minute?

• 165

• 8293.80

• 1036.73

• 2640

How is linear speed calculated from angular speed?

• By multiplying the angular speed by the radius

• By dividing the angular speed by the radius

• By adding the angular speed to the radius

• By subtracting the radius from the angular speed

What is the linear speed of the wheel in inches per minute?

• 2640

• 1036.73
