Question 7.2. A body of mass 0.025 kg attached to a spring is displaced through 0.10 m to right of mean position, if spring constant of spring is 0.4N/m and its velocity at the end of this displacement is 0.4 m/s. Calculate (i) Time period “T” (ii) Frequency ‘f’ (iii) Angular speed ‘ω’ (iv) The total energy (v) the amplitude of its motion (vi) The maximum velocity (vii) The maximum acceleration.
