(a) Write the equation for centripetal force, and substitute thevalues T and L appropriately. Then with a bit of elementaryalgebra,rearrange the equation so that it solves for mass.
(b) Show that the mass of the puck is 5 kg when the length of thestring is 2 m, string tension is 10 N, and the tangential speed ofthe puck is 2 m/s.

An air puck of mass 0.29 kg is tied to a string and allowed to revolve in a circle of radius 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 0.7 kg is tied to it. The suspended mass remains in equilibrium while the puck on the tabletop revolves. what is the tension on the string (in N)? what is the force causing the centripetal acceleration on the puck (in N)? what is the speed of the puck (in m/s)?

A pendulum is made of a ( 251.3 ± 0.1) g mass and a string that is( 1.3±0.005)m long. If the mass has a speed of (1.3± 0.1) m/s atthe bottom of the swing:
A) Calculate the centripetal acceleration of the mass ( withuncertainty).
B) use Newton's second law of motion to obtain the equation neededto solve for the tension. Note the free body diagram must beincluded.
C) Calculate the tension in the string ( with uncertainty).
D) Determine the centripetal force acting on the mass ( withuncertainty)

A string of length (L) and mass (M) vibrating with a linearfrequency (f) and amplitude (A) has a periodic transversedisturbance traveling its length at a speed (v).

L = 2.00 meters = length of string
M = 0.005 kg = mass of string
f = 100 Hz = linear frequency of vibration
A = 0.030 meters = amplitude of the period transverse wavetraveling in the string
v = 20 m/s = speed of the transverse wave traveling down thestring

Determine the following:
a) Wavelength of the periodic disturbance
b) Wave number
c) Tension in the string
d) Fundamental frequency in the string
e) Maximum transverse speed and maximum transverse acceleration ofany small bit of string
f) Displacement of the bit of string at x = L/4 when t = 0.5seconds
g) Speed of the bit of string at x = 3L/4 when t = (1/80)seconds
h) Average total energy of waves on the string
i) Average rate at which energy is transmitted along the string
