Title: Studying the Relationship Between Drop Height and Bouncing Height of a Ball: You can drop balls of different materials (e.g., rubber, plastic, ping pong) from various heights onto a flat surface and measure the height of their bounce using a ruler.   Introduction: (What do you expect to learn? What is the purpose of this lab? List any questions this experiment will answer.)       Hypothesis: (Predict the outcome(s) of the experiment, must be in an “if…then format.)           Materials: (What equipment and materials did you need for this experiment assignment? Describe how any equipment was connected. Also mention any special hardware or connections. List the name and amount of each item used.)             Procedures: (What steps did you take to accomplish this lab assignment? Include Safety Precautions.)                       Data Collection: (Record the data that is required at each step of the lab: tables, charts, graphs, sketches, etc.)             Data Analysis: (Explain you…

A traveler at an airport takes an escalator up one floor as in the figure below. The moving staircase would itself carry him upward with vertical velocity component v between entry and exit points separated by height h. However, while the escalator is moving, the hurried traveler climbs the steps of the escalator at a rate of n steps/s. Assume that the height of each step is hs. (a) Determine the amount of chemical energy converted into mechanical energy by the traveler's leg muscles during his escalator ride given that his mass is m. (Use any variable or symbol stated above along with the following as necessary: g.) energy = (b) Determine the work the escalator motor does on this person. (Use any variable or symbol stated above along with the following as necessary: g.) work =
