The total cross-sectional area of the load-bearing calcified portion of the two forearm bones (radius and ulna) is approximately 2.3 cm2. during a car crash, the forearm is slammed against the dashboard. the arm comes to rest from an initial speed of 80 km/h in 5.8 ms. if the arm has an effective mass of 3.0 kg, what is the compressional stress that the arm withstands during the crash?

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
