Harmonic Motion and and Spring Scale

At an outdoor market, a bunch of bananas is set on a spring scale to measure the weight. The spring set the full bunch of bananas into vertical oscillatory motion. The motion is harmonic with an amplitude of 0.15 m. The spring of the scale has a force constant k = 332 n/m. It is observed that the maximum speed of the bananas is 1.56m/s.
What is the mass of the banana bunch in units of kg?

Solution Preview

When a mass m attached to a spring of force constant K, the period of oscillation is given by

T = 2pi*sqrt(mass/K)

the ...
