Question
In the figure, a solid brass ball of
mass m will roll smoothly along a
loop-the-loop track when released
from rest along the straight
section. The circular loop has
h
R
radius R, and the ball has radius.
r <R.
NOTE: Give your answer in terms of the
variables given, and g.
(a) What is h if the ball is on the verge of leaving the track when it
reaches the top of the loop?
h
=
(b) If the ball is released at height h
=
6R, what is the magnitude
of the horizontal force component acting on the ball at point Q?
F =
