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,

Some help

Look for Kinematics, and Instantaneous center of rotation.

Hi Jon,

Calculating the deceleration of a moving vehicle using angular acceleration can be a useful approach. To convert the angular acceleration (dw/dt) to linear acceleration (a), you can use the formula a = r * dw/dt, where r is the radius of the wheel.

So, to calculate the deceleration (a) in m/s^2, you will first need to determine the radius of the wheel. Then, you can plug in the value of dw/dt in rad/s^2 and solve for a. Keep in mind that the moments of force and moments of inertia should also be in the appropriate units.

I hope this helps. Good luck!
