A 1000-kg car has four 10-kg wheels. What fraction of the total kinetic energy of the
car is due to rotation of the wheels? Assume that the wheels have the same rotational inertia as disks
of the same mass and size. Explain why you do not need to know the radius of the wheels?

where is the answer Ashik i didn't find it also, we will fail :(
b) because the I= 1/2 mr^2 w^2
w^2= v^2/r^2 so the "r"s cancel out
w^2= v^2/r^2 so the "r"s cancel out
