Question
An air puck of mass m, = 0.26 kg is tied to a string and allowed to revolve in a circle of radius R = 1.1 m on a frictionless horizontal table. The other end of the string passes through a hole in the center of the
table, and a mass of m, = 0.7 kg is tied to it (see the figure below). The suspended mass remains in equilibrium while the puck on the tabletop revolves.
(a) What is the tension in the string (in N)?
N
(b) What is the horizontal force acting on the puck (in N)?
(c) What is the speed of the puck (in m/s)?
m/s
