Because it's a power to turn the wheels of industry
 
        
             
        
        
        
Acceleration = ( final velocity - intial velocity ) / time
= (60-0)m/s / 3s
= 20 m/s2
 the answer is a

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.
 
        
             
        
        
        
I’m going to use molasses as an example of a substance.
The mass and volume both change when changing the amount of molasses. 
However, the density does not change. This is because the mass and volume increase at the same rate/proportion!
Even though there is more molasses (mass) in test tube A, the molasses also takes up more space (volume). Therefore, the spacing between those tiny particles that make up the molasses is constant (does not change). 
The size or amount of a material/substance does not affect its density.
