I think you're saying that once you start pushing on the cars, you want to be able to stop each one in the same time.
This is sneaky. At first, I thought it must be both 'c' and 'd'. But it's not
kinetic energy, for reasons I'm not ambitious enough to go into.
(And besides, there's no great honor awarded around here for explaining
why any given choice is NOT the answer.)
The answer is momentum.
Momentum is (mass x speed). Change in momentum is (force x time).
No matter the weight (mass) or speed of the car, the one with the greater
momentum is always the one that will require the greater (force x time)
to stop it. If the time is the same for any car, then more momentum
will always require more force.
Answer:
The distance in kilometers is 4012 ×
km.
Explanation:
We know that the conversion of 1 millimeters is equal to 
meter. And then the conversion of 1 meter is equal to km. Then the conversion of 1 millimeter to km will be
1 mm = m
1 m = km
So, 1 mm = × km = km.
As here the the distance is 4012 mm, then the distance in km will be
4012 mm = 4012 × km.
So the distance is 4012 × km.
