How would the kinetic energy of a 12,000-kg train compare with the kinetic energy of a 900-kg compact car of both were traveling at the same speed?
Answered by R_scott
the K.E. is proportional to the mass

the mass of the train is about 13 times the mass of the car
... so it has about 13 times the K.E.
