The difference between a car hitting a wall vs. a car hitting a hay stack is

• the Impulse on the car hitting the wall is greater
• the change in momentum of the car hitting the wall is greater
• the force on the car hitting the hay stack is greater
• the collision time of the car hitting the hay stack is greater

The impulse-momentum theorem states that

• the impulse on an object is equal to the change in momentum it causes 
• the force on a moving object is equal to the magnitude of the impulse.
• the impulse on an object is greater than the change in momentum it causes 
• the impulse on an object is less than the change in momentum it causes
