Answer:

600m/s²

Explanation:

Given parameters:

Mass of car  = 600kg

Impulse  = 18000kgm/s

Time  = 0.05s

Unknown:

Acceleration  = ?

Solution:

To solve this problem, let us find the force that cause the impact first;

          Impulse  = Force x time

          Force  = [tex]\frac{impulse}{time}[/tex]    = [tex]\frac{18000}{0.05}[/tex]    = 360000N

So;

        Force   = mass x acceleration

         Acceleration  = [tex]\frac{Force }{mass}[/tex]    = [tex]\frac{360000}{600}[/tex]    

         Acceleration  = 600m/s²
