At an outdoor market, a bunch of bananas is set on a spring scale to measure the weight. The spring sets the full bunch of bananas into vertical oscillatory motion, which is harmonic with an amplitude 0.21 m. The maximum speed of the bananas is observed to be 1.92 m/s. What is the mass of the bananas? The spring of the scale has a force constant 223 N/m. Answer in units of kg.
