A1090 kg car has four 12.7 kg wheels. when the car is moving, what fraction of the total kinetic energy of the car is due to rotation of the wheels about their axles? assume that the wheels have the same rotational inertia as uniform disks of the same mass and size.

Explanation:

To develop this exercise we proceed to use the kinetic energy equations,

In the end we replace

Here

meaning the 4 wheels,

So replacing

So,

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
