have a maximum mass max M and the wheel maximum radius is max R . Your job is to advise them on the
following issue: a) Heavy wheel and light body, b) Light wheel and heavy body. Assume the wheels are
considered as homogeneous disks and g = 9.81m / s2 , h = 10m.
1) Plot the velocity of the car as a function of the ration r = Mwheel/Mmax. Use practical value of r
2) Advise the team on their choice.
The following are the main equations I need help with:
a) Wheel Mass Moment of Inertia;
b) Work Done as the Car Rolls Down the Hill
