If a car with a mass of 4000 kg is accelerating at a rate of 2 ms and hits a tree what force does it have

That depends on the car's speed at the moment of impact, and how long it takes to stop after the impact.

It is NOT 8,000N. That answer would come from a totally incorrect application of " F = m a " . 8,000 Newtons is what it takes to accelerate that car in the first place, long before it hits the tree.

Force can be described as either a pull or a push

Now when a body with mass and acceleration hits an object, we say a collision has taken place, hence there will be transfer of energy within the system

Give data

mass = 4000kg

acceleration = 2m/s^2

We know that force is given as

Force = mass x acceleration

Substitute our given data into the expression for force

Force = 4000 x 2Force = 8000N

answer: electrons

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
