would the maximum speed attained down the hill be 38.36m/s? using v=sqrt2gh? or is velocity not the same as maximum speed?

it mentions that it is in an urban area so i assumed that the speed limit would be 30 therefore the speed of the car would be 30?? i don't know though

change in kinetic energy of car to rotational energy of flywheel so would have 0.5MV^2=0.5Iw^2 => w^2=(M/I)V^2 => w=7.79V and then the drop from 30mph to zero needs to be taken into account somehow. am i right?

I need a bit of help with a few questions. In a hybrid vehicle a flywheel is used to capture the energy of the car during braking. If the car has a total mass of 850kg and the flywheel has a mass-moment of inertia equal to 14kgm2 determine the speed of the flywheel when the car stops for...
