Question

A block of mass 5kg executes simple harmonic motion under the restoring forces
a spring, The amplitude and the time period of the motion are 0.1m and 3.14s
respectively. The maximum force exerted by the spring is​

Answer 1

hope it will help you...

Answer 2

Answer:

The maximum force exerted on the block is kA when the block is at the extreme position.

The angular frequency ω=2πT=2s−1

The spring constant =k=mω2

=(5kg)(4s−2)=20Nm−1

maximum force =kA=(20Nm−1)(0.1m)=2N
