3.)
You are provided with a light spring meter scale and a known mass. How will you find the time period of oscillation of the mass attached to the spring without the use of clock.
4.)
A mass m attached to a spring oscillates with the period of 2 seconds. If the mass is increased by 2kg,the period increase by 1 second. Find the initial mass m, assuming that hooke's law is obeyed.
5.)
Show that for a particle executing SHM the maximum potential energy is same as that of maximum kinetic energy which is equal to the total energy.
6.)
