Question: A B) B C) a. b. A A E) B a. Draw a Free Body Diagram of all external forces acting on the system.

A B) B C) a. b. A A E) B a. Draw a Free Body Diagram of all external forces acting on the system. b. What is the observed acceleration of the system? c. What is the force of tension between the car and the truck? F) Figures not drawn to scale 1) (Use Figure G) A 1000. kg car is tied to a 2500 kg truck using a very strong, but massless rope. A force pulls on the car with 4500. N of force. Rolling friction is very, very low and can be ignored. 12 B 2) (Use Figure B) A 600 g mass is hung from a perfect physics pulley. A thin, but strong thread is used to attach the mass to another mass of 1500 g that is on a flat, frictionless table. Draw a Free Body Diagram of all external forces acting on the system What is the acceleration (including direction) of the 1500 g mass? c. Draw a Free Body Diagram for each mass of all forces acting on that mass d. What is the force of tension acting on the 600 g mass? e. If there was friction ( = 0.095) between the 1500g mass and the table as the mass moved, what is the net acceleration of the system now?
