Marion rides her racing bicycle at a speed of 8 m/s. the bicyle wheels have a radius of 34 cm.
a. what is the angular speed of the wheels?
b. how many times does each wheel go around during a 10 minute ride?

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

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
