A 200 g puck revolves in a circle on a frictionless table at the end of a 50.0 cm long string. The puck's angular momentum is 3.00 kg⋅m2/s.
Part A
What is the tension in the string?
Here,
m = 0.20 Kg
L = 0.50 m
angular momentum = 3 Kg.m^2/s
angular momentum , 3 = m * v * L
3 = 0.20 * 0.50 * v
v = 30 m/s
tension in the string = m * v^2/L
tension in the string = 0.20 * 30^2/0.50
tension in the string = 360 N
the tension in the string is 360 N

A puck (mass 200 g) slides on frictionless ice in a circle because it is attached to a 25-cm-long string. What is the tension of the string if the puck goes around in a circle once every second?
An air puck of mass 0.23 kg is tied to a string and allowed to revolve in a circle of radius 1.2 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 0.9 kg is tied to it. The suspended mass remains in equilibrium while the puck on the tabletop revolves. a) What is the tension in the string? (b) What is the force...
an ice puck of mass m revolves on an icy surface in a circle at speed v at the end of a horizontal string of length L. the tension in the string is T. write the equation for centripetal force, and substitute the values T and L appropriately. then with a bit of elementary algebra, rearrange the equation so that it solves for mass. find the mass of the puck when the length of the string is 2.0 m, string...
