states of matter problem, me = Total cross-sectional area of a load-bearing calcified portion of 2 forearm bones is approx 2.4cm squared. During a car crash, the forearm is slammed against the dashboard. the arm comes to frest from intiial speed of 80 km/h in 5.0 ms. If arm has effective mass of 3.0 kg and bone material can withstand a max compressional stress of 16x10^7 Pa, is arm likely to withstand crash? Not sure on which equation to use due to not really getting the conceptual side of the question, please help!
