2)An ice skater with a mass of 50 kg glides freely on smooth, level ice. She experiences a 3.0 N frictional force from the ice and an air resistance of 1.0 N. a) What is the net force acting on her? b) What is her acceleration?

3) Jill and Brian's car ran out of gas. They push the 1000-kg car with a force of 350 N on a level road. The road exerts a force of friction on the car equal to 125 N.

a) Draw a free body diagram of the car and identify clearly all of the important

forces acting on the car.

b) Find the acceleration of the car as they push it.

5) A 3.0 kg book is lying on a table.

a) Find the weight (in newtons) of the book and the normal force exerted by the

table on the book.

b) Later a 7.0 kg box is placed on top of the book.

Find the normal force that the table now exerts on the 3.0 kg book and the normal force the book exerts on the 7.0 kg box. It may be helpful to draw free body diagrams.

6) In the 1934 film, It Happened One Night, Clark Gable was standing inside a stationary bus in front of Claudette Colbert, who was seated. When the bus suddenly started moving forward, Clark fell into Claudette's lap. Explain this in detail in terms of Newton's laws.

7) Sarah is sitting on a chair. What two vertical forces are acting upon Sarah? Are these forces an action/reaction pair defined by Newton's third law of motion? Explain your answer.

8) A 5.0 kg bucket of water is raised from a well by a rope. If the upwards acceleration of the bucket is 2.0 m/s2, what is the force of tension exerted by the rope on the bucket?
