Question

A mass 0.9 kg, attached to a horizontal spring, executes SHM with an amplitude A_1. When this mass passes through its mean position, then a smaller mass of 124 g is placed over it and both masses move together with amplitude A_2. If the ratio A_1A_2 is -1, then the value of will be____.

Accepted Answer

Correct answer: 16. (16) 12kA^2= p^22m ⇒ ( A_1A_2 )^2= m_2m_1= 1024900 ⇒ A_1A_2= 3230= 1615= 1616-1 ∴ =16
