Part A (Using the Concepts): Multiple Choice: If calculations are required, the mark for the strategy will worth more marks and the final answer will be worth one mark. 1. A box sits on top of a flat horizontal surface while it is pulled horizontally. The box does not move. The complete list of force(s) acting on the box is/are. a. the force of gravity b. the force of gravity and the normal force c. the force of gravity, the normal force, and the applied force. d. the force of gravity, the normal force, the applied force, and static friction 2. You hit a puck with a hockey stick and the puck slides across the ice and gradually slows down. After the puck leaves the stick, the correct list of force(s) acting on the puck is/are a. the force of gravity b. the force of gravity and the normal force c. the force of gravity, the normal force, and kinetic friction d. the force of gravity, the normal force, kinetic friction, and the applied force 3. Which list contains only an action-at-a-distance force(s)? a. the normal force and the applied force b. kinetic and static friction c.the force of gravity d. all of the above 4. You throw a baseball toward a friend. After you let go of the ball, the correct force(s) acting on the ball is/are a.the force of gravity b.the force of gravity and the applied force from your hand on the ball c.the force of gravity and the normal force d.the force of gravity, the applied force from your hand on the ball, and the normal force d. 5. Which of the following statements is/are true about FBD's? a. the arrows represent all the forces acting on the object b. the length of each arrow is proportional to the magnitude of the force c. a positive direction is indicated and used throughout the problem d. all of the above Part B (Putting the Concepts to Work):Using your reading, answer the following questions. Give your answer as well as your strategy for determining your answer. As part of your answer, give the page number in the reference material or the website that you used to find the answer to the question. In the following, state the direction of each force acting on the object in italics. Explain your reasoning. 6.A box slides across the floor towards the east. 7.The force of gravity on a ball thrown towards the west. 8.The force of the wind against a runner headed north. 9.A box at rest on a rough table is pushed forward but does not move. 10.A car starts from rest and accelerates uniformly reaching a velocity of 24 m/s [S] in 17 s. Calculate the average acceleration. 11.A skater accelerates uniformly from an initial velocity of 3.0 m/s [E] to 9.0 m/s [E] in 8.0 s. Calculate the average acceleration. 12. A truck travelling initially at 19 m/s [W] brakes smoothly and stops in 5.3 s. Calculate the average acceleration. 13. A space probe from Earth lands on a distant planet to gather data. In one experiment, the probe drops an object, which reaches a velocity of 8.5 m/s [down] after 1.2 s. Calculate the acceleration due to gravity on this planet
