1) A Mack truck weighing 45,000 lbs. is speeding down the highway at 120 mi/hr when it crashes head-on into a parked Ford Escort weighing 2,500 lbs.
a) What is the ratio of the force of the truck on the Ford divided by the force of the Ford on the truck?
b) During the collision, both the car and the truck are changing their velocities. What is the ratio of the acceleration of the Ford divided by the acceleration of the truck?
c) What principle(s) or law(s) are you using to arrive at your answers? Show your calculations and explain your reasoning.
