I notice the wheels on my bicycle spin in a circular motion as I am pedaling. I know that the wheels have a radius of 0.31m and they are going at a speed of 15 m/s. What is the centripetal
acceleration of my bike wheel?

Guess method

Acceleration, a = 750m/s²

Explanation:

Given the following data;

Radius, r = 0.31m

Velocity, v = 15m/s

To find the centripetal acceleration;

Substituting into the equation, we have;

Acceleration, a = 750m/s²

Therefore, the centripetal acceleration of the bike wheel is 750m/s².

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
