Question

In a study conducted by an Acadia Athletic Therapy researcher, the football team was equipped for an entire season with helmets containing accelerometers. Information about every impact in practice and in games was sent to a computer present on the sidelines. The study found that the average force on a top of the head impact was 1773 N and endured for 7.6 milliseconds.

a) Using a head mass of 5.2 kg and presuming the head to be a free body, determine the velocity change in m/s experienced in such an impact.

b) What was the average acceleration in Gs (how many times gravity) experienced during the average head impact described above?
