The impulse is force x time and momentum is mass x velocity.  Something with less time will have less time to distribute force evenly and will be damaged more on impact. Momentum is another way to say inertia in motion. More mass=more inertia and more velocity is the same.
It would be much less painful to be hit by the car if it was either less mass, was going slower, or if it had more time to slow down.

When the string is being held, the potential energy is at its max. When it is released, the potential turns to mechanical before the car starts moving. When the car is in motion, the kinetic energy at is max is the same as the potential at its max due to the law of conservation of energy.

Car pushes earth, earth pushes car.
Mousetrap snaps against wood, wood snaps against mousetrap.
Rubber pushes against earth, earth pushes against rubber.
Air pushes against car, car pushes against air.

1st. Our car would never move if it was not started to move and our car would move forever if there was no friction or air resistance, etc.
2. The force our car has is directly proportional to the acceleration and inversely proportional to the mass.
3. When our car pushes against the ground, the ground is also pushing against the car. For every force there is an equal and opposite reaction.

mass x initial acceleration - mass x average acceleration
so
131.5x6.12
f=804.78
131.5x1.44
f=189.36
so
804.78-189.36

FORCE OF FRICTION=615.42
