How to Calculate Vehicle Deceleration from Angular Acceleration?

[johnny_heart]

hi all,

just wanted some advice on calculating a rate of deceleration of a moving vehicle, if we work out the angular acceleration of the wheel.

so angular acceleration is dw/dt and is given as dw/dt=(m1-m2)/I

(i.e moments of force divided by moments of Inertia)

dw/dt is rad/s^2 and my deceleration needs to be m/s^2

some help is greatly appreciated,

Look for Kinematics, and Instantaneous center of rotation.
