An elastic cord vibrates with a frequency of 2.5 Hz when a mass of 0.63 kg is hung from it.
What is its frequency if only 0.32 kg hangs from it?

An elastic cord vibrates with afrequency of 3.0 Hz when a mass of 0.57 kg is hung from it. Whatwill its frequency be if only 0.39 kg hangs from it?Hz
A spring vibrates with of frequency of 3 Hz when a mass of 1 kg is hung from it. Find the spring costant K. If a 3 kg mass were added to the 1kg mass, what would be the resulting frequency?
A 15.5 kg mass vibrates in simple harmonic motion with a frequency of 17.73 Hz. It has a maximum displacement from equilibrium of +13.2 cm at time, t = 0.00 s. The displacement from equilibrium of the mass at time, t = 1.25 s is cm.
A mass m at the end of a spring vibrates with a frequency of 0.86 Hz . When an additional 660 g mass is added to m, the frequency is 0.65 Hz . What is the value of m? Express your answer using two significant figures.
A vertical elastic cord is stretched 0.306 m when a mass 1.66 kg is attached to it. The cord is then stretched an additional 0.114 m and released from rest. Assuming the cord is an ideal linear spring, how long does it take for the mass to reach its original equilibrium position? HINTS: First find the elastic constant of the elastic cord, using the fact that the gravitational weight mg of the mass is balanced by the upward pull of...
A violin string vibrates at 294 Hz when unfingered. At what frequency will it vibrate if it is fingered one-third of the way down from the end? (That is, only two-thirds of the string vibrates as a standing wave.)
An elastic cord is 61 cm long when a weight of 75 N hangs from it but is 85 cm long when a weight of 210 N hangs from it. What is the “spring” constant k of this elastic cord? also, find the frequency of the motion with the 210N object hanging on it (Physics 'Algebra base')
An object with the mass m= 2.0 kg hangs from a cord around a light pulley. The length of the cord between point P and the pulley is L= 2.0 m (Ignore the mass of the vertical section of the cord) a) When the vibrator is set to a frequency of 160 Hz, a standing wave with six loops is formed. What must be the linear mass density of the cord in kg/m? b) How many loops (if any) will...
A fisherman's scale stretches 4.0 cm when a 2.5 kg fish hangs from it. A) What is the spring stiffness constant?? B) What will be the amplitude of vibration if the fish is pulled down 2.5 cm more and released so that it vibrates up and down? C) What will be the frequency of vibration if the fish is pulled down 2.5 cm more and released so that it vibrates up and down?
When unfingered, a string on a guitar vibrates at 554 Hz. What frequency will the string produce when fingered one third of the way from the end, that is only two thirds of the string can vibrate? Answer Hz Check When unfingered, a string on a guitar vibrates at 554 Hz. What frequency will the string produce when fingered one third of the way from the end, that is only two thirds of the string can vibrate? Answer Hz Check
