Question

An object of mass m is attached to a spring with spring constant k = 170 N/m. At time t = 0 the object is pulled to a distance of 0.18 m from its equilibrium position. The surface on which the object moves is frictionless and the spring is within its elastic regime. What is the mass of the object if it oscillates with a frequency f = 2.90 Hz when it is released?

Express the result in the unit [kg] and to three significant figures. If you must use scientific notation, please enter as follows: e.g. 0.000123 = 1.23E-4. Only answer in numerical values, no units. For negative numbers, leave no space between the negative sign and the number: e.g. right: -1.00, wrong: - 1.00.

Explanation / Answer

f = 2.9 Hz ;

= 2 f ;

= 2 * 2.9 = 18.221 ;

= ( k / m ) ;

18.221 = ( 170 / m ) ;

m = 0.5120 kg <--------ans
