Answer:
Small sports car.
Explanation:
Lets take
mass of the small car = m
mass of the truck = M
As we know that when car collide with the massive truck then due to change in the moment of the car both car as well as truck will feel force.We also know that from Third law of Newton's ,it states that every action have it reaction with same magnitude but in the opposite direction.
Therefore
F = m a
a=Acceleration of the car

F= M a'
a'=Acceleration of the massive truck

Here given that M > m that is why a > a'
Therefore car will experiences more acceleration.
There are two ways to find energy. Energy=F*d=mv^2. We can use this relationship to find v:
I think it would be that it has no atmosphere
Answer:
-10m/s
Explanation:
only the magnitude of the velocity will change due to the change in direction of the car.
