Question

what is the maximum speed of a 34-g object bouncing on a spring (k=78.1 N/m) with an amplitude of 3.5-cm?

Answer 1

The maximum speed of the mass is 1.67 m/s.

Step-by-step explanation:

We have,

Mass of object is 34 g or 0.034 kg

Spring constant of the spring is 78.1 N/m

Amplitude attained by the object is 3.5 cm or 0.035 m

It is required to find the maximum speed of the object in this spring mass system. The maximum speed is given by :

`v=A\omega`

`\omega=\sqrt{(k)/(m)}`

`v=A\sqrt{(k)/(m)}`

Plugging all the values in above formula,

`v=0.035* \sqrt{(78.1)/(0.034)}\\\\v=1.67\ m/s`

So, the maximum speed of the mass is 1.67 m/s.
