1. A child is coasting on his bicycle, when the bicycle collides with a fence. Using Newton's first law, explain what will likely happen to the child. 2. Use Newton's second law to explain why two objects that appear identical from the outside do not travel the same distance when the same amount of force is applied to them. 3. During a slap-shot, 55 N of force is exerted on a 0.15 kg hockey puck. Neglecting (ignoring) friction, what will the puck's acceleration be? 4. A book is lying on a table. State two sets of action-reaction forces associated with the book. 5. You are shown a heavy crate that you must pull to a finish line, using a rope. However, you are told that you must exert a force forwards on the crate and that the crate will exert an equal force backward on you. Before you get to pull the crate to the finish line, you must explain how it is even possible to move the crate if these are equal, but opposite forces.
