The pendulum of a clock is replaced by a spring mass system with the spring having spring constant `0.1Nm^-1`. What mass should be attached to the spring?

Text Solution

Verified by Experts

The correct Answer is:
`=0.01kg~~10gm`
`k=0.1N/m`
`T=2pisqrt((m/k))=2sec`
[Time period of pendulum of a clock =2 sec]
`So pi^2(m/k)=1`
`:.m=k/pi^2=0.1/10`
`=0.01kg~~10gm`

A block whose mass is 1kg is fastened to a spring. The spring has a spring constant of 50 Nm^(-1) . The block is pulled to a distance x=10 cm from its equilibrium position at x=0 on a frictionless surface from rest at t=0. Calculate the kinetic, potential and total energies of the block when it is 5 cm away from the mean position.
