Question

38. A puck of mass m, is tied
QIC to a string and allowed
Sto revolve in a circle of
m1
R
radius R on a friction-
table
less, horizontal
The other end of the
string passes through
a small hole in the cen-
m2
ter of the table, and
an object of mass m2 is
tied to it (Fig. P6.38)
The suspended object
remains in equilibrium while the puck on the tabletop
revolves. Find symbolic expressions for (a) the tension in the
string, (b) the radial force acting on the puck, and (c) the
speed of the puck. (d) Qualitatively describe what will hap-
pen in the motion of the puck if the value of m, is increased
by placing a small additional load on the puck. (e) Qualita
tively describe what will happen in the motion of the puck
if the value of m, is instead decreased by removing a part of
the hanging load
