4.1.1.P3

Suppose you are sitting in a car that is speeding up. Assume the car has rear wheel drive. Draw a system schema for this situation.  Then draw well-separated force diagrams (free-body diagrams) of the following objects:

• your own body;
• the seat in which you are sitting (apart from the car);
• the car (apart from the seat);
• the road surface where the tires and the road interact. 

• Describe each force in words; show larger forces with longer arrows.
• Identify the Newton's third law pairs.  (How are they visible in the system schema?)
  

Explain carefully in your own words how the force imparting acceleration to the car originates.
