### a gun fires a bullet. does the gun or the bullet experience a greater force, and which of newtons 3 laws explains this fact?

the gun and the bullet experience the same force as a consequence of newtons 3rd law.

all of these

### if a non-rotating object as no acceleration, then we can say for certain that it is

in mechinical equilibrium

the force of the collision on the truck is equal to the force of collision on the car.

no

### strange as it may seem, it is just as hard to accelerate a car on a level surface on the moon as it is here on the earth. this is because

the mass of the car is independent gravity
