Answer:
Part A) The angular speed of the wheels is
Part B) Approximately 2,247 revolutions
Explanation:
Part A) What is the angular speed of the wheels?
we know that
The Angular speed is equal to divide the Linear speed by the radius
Let
s -----> the linear speed in m/sec
r -----> radius in m
w ----> angular speed in rad/sec
we have
substitute
Part B) How many times does each wheel go round during a 10-minute ride?
we know that
As the wheel rotates one time, a point on the wheel rotates 2π radians.
Remember that
To find out the number of rotations divide by 2π
Approximately 2,247 revolutions
