An educational toy company, “EPH Swartz!” is looking for a new toy that will revolutionize the toy market. Your job is to design and construct a creative toy based on physics that you feel will be widely in demand and increase revenue for the company and you do a write-up paper that includes how the idea arose for the toy (1Page), a description of the physics behind the toy’s function & GPS correlation, extremely detailed (at least 2Pages) and instructions for how to use the toy or play the game (must be clear and precise).

When you push downward on a book at rest on a table, you feel an upward force. does this force depend on friction? defend your answer.

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.

State the below theories and give the name of the writer of the theory 1. wave theory 2. quantum theory 3. corpuscular theory 4. electromagnetic theory
