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?

Answer:

Acceleration, a = 750m/s²

Explanation:

Given the following data;

Radius, r = 0.31m

Velocity, v = 15m/s

To find the centripetal acceleration;

[tex] Acceleration, a = \frac {v^{2}}{r}[/tex]

Substituting into the equation, we have;

[tex] Acceleration, a = \frac {15^{2}}{0.31}[/tex]

[tex] Acceleration, a = \frac {225}{0.31}[/tex]

Acceleration, a = 750m/s²

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