The second car accelerates
The alligator would die and you would probably get a big dent in your bumper.
Their combined momentum will be equal to the first boxcar's original momentum before the collision.
Balanced forces occur when a body is at rest, and when a body is moving at a constant speed in a constant direction.
That would depend on the velocity of the soccer ball not at rest.
An object has kinetic energy when it is moving and not when it is at rest. When it is at rest it has potential energy.
An object at rest cannot start moving with no forces.
With difficulty.Remove bumper and the rest is obvious
Being at rest is a relative term. Relative to earth we are at rest when we are sitting down. However, you are moving because the earth is moving its orbit around the sun.

That means that something is at rest, i.e., not moving.
At rest.
