# Thread: Average Acceleration physics question- Please someone help me

1. A Bicycle wheel is rotating at 29.0 rpm. It Breaks & Stops at 2.4 rotations. Find average (negative acceleration)In rad/s ^2?

2. Homework stuff is not done for you here.

Here's a clue.
What would be the average angular velocity during the deceleration assuming it was constant deceleration?

I am quite sure that you solved a similar problem for the linear case:

All you need is to transfer your experience to the rotational case. You can start by replacing the linear distance with the angle and the linear speed with the angular speed
