An automobile has a total mass of 1700 kg. It accelerates from rest to 40 km/h in 10 s. Assume each wheel is a uniform 32 kg disk. Find, for the end of the 10 s interval,
(a) the rotational kinetic energy of each wheel about its axle,
(b) the total kinetic energy of each wheel, and
(c) the total kinetic energy of the automobile. Please Show all Work
