PRE LAB ASSIGNMENTS
Which of the following is an inertial frame
(
where when no force is applied, a body at rest will
stay at rest, a body in motion will remain in constant velocity motion
)
?
a
. In an airplane that is at cruising altitude, flying straight ahead, without experiencing turbulence;
b
. In a car that is running on a straight highway and switching lanes to avoid colliding into
another vehicle;
c
. In a roller coaster that is at the highest point of the whole round;
d
. On a spinning top whose location barely changes;
e
. On a fixed point on earth which spins roughly a turn relative to the sun in
2
4 hours.
For the setup to the right, draw the free body diagram for
the mass
, assuming no friction between the mass and the
surface it is sliding on
.
For the same setup, draw the free body diagram for the mass
.
Use
∑
=
to write down the equation of motion for the mass
, and then
∑
=
to
write down the equation for mass
. Due to the string,
and
have the same magnitude of
acceleration, one to the right and the other downward. Solve
.
