Experiments on cadavers demonstrate that the threshold for breaking the hip is about

$4$kN for the proximal femur. $($a$)$ Estimate the forces on your hip assuming you fall

sideways keeping your leg straights. In doing so$,$ you will fall like an inverted pendulum.

Also, assume that the tissue around your hip deforms by about $4$ cm on impact, and it

behaves like a linear spring. $($b$)$ Will your hip break? $($c$)$ Does your answer depend on

your body mass? $($d$)$ Does your answer depend on how long your legs are? Use your

estimates of your own body mass and leg length for this answer. $(5$ pts$)$
