Your supervisors at A&L Engineering have tasked you with evaluating the durability of three common materials used in the design of cell phone cases. For each material type, you have been asked to determine the force of impact of a phone dropped from a set height above the ground. Using the mass of each case and the collision time, determine the force of impact on each case material and determine which case material offers the most protection. To facilitate your analysis, you have been provided with specifications for case materials in the table below. However, you may also use your own figures for the mass of phones and test case materials. If you do use a different figure, be sure to make that clear in your analysis. As you use this data, ensure that you have made the necessary SI unit conversions: Test Material Mass Collision Time Phone only (no case) 6.2 oz. 0.01 seconds Silicone 1.7 oz. 0.05 seconds Hard Plastic 1.1 oz. 0.03 seconds Rubber 3.2 oz. 0.08 seconds Create force diagrams to model the motion for a phone dropped from a set height. You should include diagrams, with their respective force vectors, for each phone drop. In your diagrams, address the following: A) Define the height you will be using for each phone drop. As the researcher, you will choose a drop height of between 1 and 2 meters. B) Using the provided mass of 6.2 oz, or by measuring the mass of a personal cell phone, determine the mass you will be using for your calculations. Remember to add the mass of the case material. C) In your diagram, show the direction and name of each force on the cell phone both at the drop point and at the point of collision with the ground.
