Question
A 79.5kg person, running horizontally with a
velocity of +2.34m/s,jumps onto a 11.8kg sled
that is initially at rest.
a)Ignoring the effects of friction during the
collision, find the velocity of the sled and
person as they move away.
b) The sled and person coast 30.0m on level
snow before coming to rest. What is the
coefficient of kinetic friction between the sled
and the snow?
Note: the tolerance is positive negative 1 in
the 3rd significant digit
