After travelling all night, you are driving down a narrow country lane. You briefly fall asleep at the wheel, but wake up as the car moves off the shoulder of the road. You wake up but rapidly lose control of the car and it zooms off the road. You are heading towards (1) a stack of bales of hay, or (2) a brick wall. You have seconds to choose, and luckily you choose to hit the hay stack and come to a stop.

Compare in detail the cases of hitting the brick wall versus hitting the hay stack. In which scenario do you transfer more momentum? In which scenario is your impulse larger? In which scenario is the force on the car largest? In which scenario do you experience the larges acceleration? Explain why using physical principles you have learned.
