8. A 50 kg person steps off of a 1 meter
tall desk.
a) Assuming they started at rest, how fast
are they going JUST before they hit the
ground?
b) What would be the momentum of this
person, JUST before they hit the ground?
c) The interaction with the ground causes
the person to stop. What was the impulse
received by the person from the ground?
d) Let's say two different people with
identical masses step off simultaneously,
Betty and Sally. Betty is smart and listened
in physics classes so when she hits the
ground, she bends her knees causing her
to stop over 12 seconds Sally is dumb and

c) The interaction with the ground causes
the person to stop. What was the impulse
received by the person from the ground?
d) Let's say two different people with
identical masses step off simultaneously,
Betty and Sally. Betty is smart and listened
in physics classes so when she hits the
ground, she bends her knees causing her
to stop over 1.2 seconds. Sally is dumb and
doesn't bend her knees, meaning she stops
abruptly over 0.2 seconds.
i) Who receives the bigger impulse,
Betty or Sally? Explain
ii) Who experiences the larger
stopping force, Betty or Sally? Explain.
