A block with a mass of 8.00 kg on a frictionless surface is attached to a spring. The frequency is 4.00 Hz, and the amplitude is 3.00 meters.

Find the new frequency if the block is replaced with a 2.00 kg block while the amplitude is doubled.

Answer :

Answer:

ω = (K / M)^1/2 amplitude is not related to frequency

ω2 / ω1 = (M1 / M2)^1/2 = (8 / 2)^1/2 = 2

Since frequency is proportional to the angular speed

the frequency is doubled and is

f = 8 cps
