Question

An air puck of mass m1 = 0.33 kg is tied to a string and allowed to revolve in a circle of radius R = 1.3 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 m2 = 1.0 kg is tied to it (see the figure below). The suspended mass remains in equilibrium while the puck on the tabletop revolves.

An air puck of mass m1 = 0.33 kg is tied to a string and allowed to revolve in a circle of radius R = 1.3 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 m2 = 1.0 kg is tied to it (see the figure below). The suspended mass remains in equilibrium while the puck on the tabletop revolves.

Explanation / Answer

a) T = m2*g = 9.8 N

b) F = T = 9.8 N

c) F = m1*v^2/r

9.8 = 0.33*v^2/1.3

==> v = 6.21 m/s
