If it takes roughly 4,000 N to crack the average human pelvis, and Michael’s car came to a complete stop after 0.3 seconds of deceleration during the collision, how fast was he traveling in the parking lot when he collided with his employee (let’s call her Meredith)? Assume all the force of deceleration of his car was exerted on the Meredith’s pelvis, with none being exerted on brakes or opposed by friction (admittedly unrealistic).
