## Homework Statement

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 0.14 m. The maximum

speed of the bananas is observed to be 2 m/s.

What is the mass of the bananas? The

spring of the scale has a force constant

523 N/m.

## Homework Equations

The equations I have learned are Hooke's Law (-kx=F) and period of a spring = T = 2pi sqrt(m/k)

## The Attempt at a Solution

I have tried to solve this problem, but I'm not sure how I can use the amplitude and velocity to determine the period, which I would then use to find mass. THANK YOU
