phone only(no case) mass = .175767kg; collision time = 0.01 secondsSilicone mass = .0481942kg + .175767kg (phone without case mass); collision time = 0.05secondsHard plastic mass = .0311845kg + .175767kg ; collision time = 0.03 secondsRubber mass = .0907185kg + .175767kg; collision time = 0.08 secondsCalculate velocity before impact and deceleration at impact[We divide the drop into two phases. The first phase is from the drop to the moment of first contact with the floor. The phone starts from rest, drops the distance you have chosen as the height, and is under the influence of gravity. This is a basic free fall problem, find the final velocity just before it hits the floor. The second phase is the deceleration at impact. The final velocity of phase one becomes the initial velocity of phase two. Acceleration is change in velocity over time. For each case type, you are given the length of time from first contact with the floor until the phone comes to rest.]

Calculate the force of impact

[Using the acceleration you have just calculated and the mass of the object, determine the force of impact. Remember to adjust the mass as needed throughout this step]
