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. 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
As the researcher, you will choose a drop height of between 1 and 2 meters.
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.
Use the information provided in your case specification document to calculate the velocity before impact and deceleration at impact. Remember that deceleration is represented as negative acceleration in force equations. In your calculations, assume a standard free-fall acceleration during the fall, and a velocity of 0 m/s after the impact. You should include calculations for the following scenarios:
A) A phone without a case
B) A phone
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.

Farmer a has a deep well and needs a lot of water for her animals and crops. her neighbor, farmer b, has a shallower well. he needs less water than farmer a because his farm is smaller. in years of drought, sometimes farmer b can't get any water from his wells. what can farmer b do to decrease the likelihood of his well running dry?

Pl i beg u so much now propane burns in oxygen to produce carbon dioxide and steam. the unbalanced equation for this reaction is: c3h8 + o2 → co2 + h2o use coefficients to balance this equation. a) c3h8 + 3 o2 → 3 co2 + 4 h2o b) c3h8 + o2 → 3 co2 + 4 h2o c) c3h8 + 5 o2 → 3 co2 + 4 h2o d) 2 c3h8 + 5 o2 → 3 co2 + 4 h2o
