Quiz 5 (Homework Set #7)
Name:
UFID:
Formula sheets are not allowed. Do not store equations in your calculator. You have to
solve
problems on your own; memorizing final algebraic expressions from homework assignments and
just plugging numbers into them will not give you full credit. Leave all your work.
________________________________________________________________________________
In the figure below, a 5.00kg stationary block explodes into two pieces
L
and
R
that slide across a
frictionless floor and then into regions with friction, where they stop. Piece
L
encounters a
coefficient
of
kinetic
friction
μ
L
=
0.500 and
slides
to
a
stop
in
distance
d
L
=
2.00
m.
Piece
R
encounters a coefficient of kinetic friction
μ
R
= 0.400 and slides to a stop in distance
d
R
=
4.00 m.
a) What is the velocity of the center of
mass
of
the
system
after
the
explosion?
The velocity of the center of mass
