Answer:
Yes
Explanation:
The truck has momentum since it is moving and momentum is a product of mass and velocity. After impact, part of momentum that the truck had is transferred to the car hence the car initially at rest moves a significant diatance. Here, we utilize the formula MV= (m+M)v where M and V represent mass and velocity of the truck while m is the mass of car, v is the common velocity. Note that some letters are capital while others small, don't confuse these.

--I took the quiz--
Air resistance, or drag, affects a falling object's velocity by opposing the force of gravity. As an object falls faster, it experiences greater air resistance until it reaches a point of equilibrium called terminal velocity, where it falls with a constant speed.
Air resistance, also known as drag, significantly affects the velocity of a falling object. Initially, the velocity of an object increases as it falls due to gravity; however, it also simultaneously encounters air resistance pushing up against it. The larger the object's speed, the greater the air resistance it faces. Eventually, the object reaches a point called terminal velocity where the downward force of gravity is equal to the upward force of air resistance, causing the object to fall at a constant velocity. A practical example of this is a skydiver: as they jump from the plane, at first, their velocity increases (they speed up), but then they start to experience more air resistance until they reach terminal velocity and fall at a constant speed.
