The train is going to make several stops along its journey.
It will be important for the train to accelerate
quickdy to get back up to speed. In order to get
Tesla Model S motors until we get the combined

a) What is the minimum whole number of Tesla Motors
required to achieve accelerate the train from
0 to 324 km/hr in less than 5 Nnutes? Seperate the
acceleration into constant torque and constant
power
0.
b) How long does it take the train to accelerate
from 0 to 324 km/hr with the number of Tesla
motors from part a?
c) Using Matlab plot the relocity profile as a
function of time, Is this a constant
acceleration profile?
