Answer:
3.16 m/s
Explanation:
Elastic energy in the rubber = kinetic energy of the stone
EE = KE
½ kx² = ½ mv²
v = √(kx²/m)
Given k = 200 N/m, x = 0.05 m, and m = 0.050 kg:
v = √(200 N/m (0.05 m)² / 0.050 kg)
v = √10 m/s
v ≈ 3.16 m/s
Round as needed.
The SI unit of energy is the Joule .
Any kind of energy ... electrical, mechanical, nuclear, solar,
wind etc. It's easy to change from one form to another ... we
do it every day ... and they all have the same unit.
I had to look for the options and here is my answer:
Given that a guitar string has a basic frequency of 500hz, the frequency that can be set for this into resonant vibration would be 1500 Hz. The resonant vibration here is necessary in musical instruments because it delivers a vibrating system which leads to a higher amplitude at a particular frequency.
