A crash test dummy in a car is restrained by a lap belt and subjected to a rapid deceleration of 5g to simulate a car crash. During the rapid deceleration the dummy rotates about an axis O at the point of restraint. If the upper torso mass is 50 kg, the radius of gyration about G is k=0.32m: Calculate the mass moment of inertia of the man's upper torso about 0. What is the velocity of the dummy's head relative to the car as it impacts the dashboard, (@= 45)? See the figure below for the remaining information necessary to complete the calculation R0.8 R-0.45mm
