A mass of 2kg attached to a spring of force constant 260 `Nm^(-1)` makes 100 oscillations. What is the time taken?

Text Solution

Verified by Experts

Mass attached, `m=2` kg: Force constant `k=260 N//m`
`therefore` Time period of loaded spring, `T=2pisqrt(m/k)=2pisqrt((2)/(26))=0.5509` sec
`therefore` Time for 100 oscillations `100xx0.551=55.1` sec
