• 1. Calculate the momentum of a 1000 kg sports car traveling at 30 m/s. 
• 
  
• 2. Determine the impulse needed to increase the car's speed from 30 m/s to 35 m/s. 
• 
  
• 3. In a sad turn of events, the same sports car, formerly traveling at 35 m/s, plows into a rock wall and comes to rest in 0.25 seconds. Determine the size of the force the rock wall exerts on the car. 
• 
  
• 4. How does the size of the force the rock wall exerts on the car compare to the force the car exerts on the rock wall? Briey explain. Which of Newton's laws of motion applies to your answer?
