A 2 kg rabbit starts from rest and is moving at 6 m/s after 3 seconds. What force must the rabbit exert to make this change in speed? (hint: use the velocity formula to find acceleration first, then use the force formula to solve for force)
F= 4 N

A large textbook is pushed across the desk in your classroom. What forces are acting on this textbook? Draw a Free Body Diagram showing the forces.
Upward force = FN (normal force), Downward force = Fg (force of gravity), Right force = Fapp (applied force), Left force= Ff (force of friction)
