Part F
Which of the following is the reason that we would recommend that the man bend his legs while
landing from such a fall?
Bending his legs increases the time over which the ground applies force, thus
decreasing the force applied by the ground.
Bending his legs allows him to push back up on the ground and negate some of the
effects of the force applied by the ground.
Bending his legs decreases the speed at which he hits the ground, thus decreasing the
force applied by the ground.
Bending his legs decreases his overall change in momentum, thus decreasing the force
applied by the ground.

<HW10 - Impulse and Momentum
MCAT (R) Prep: Compression of human bone
While unrealistic, we will examine the forces on a
leg when one falls from a height by approximating
the leg as a uniform cylinder of bone with a
diameter of 2.3 cm and ignoring any shear forces.
Human bone can be compressed with
approximately 1.7 × 108 N/m² before breaking. A
man with a mass of 100 kg falls from a height of
7 m. Assume his acceleration once he hits the
ground is constant. For these calculations,
10 m/s².

What is his speed just before he hits the ground?
