Teaching RSMSSB Lab Assistant (Science) 2022 Mock Test Physics Oscillations Damped Simple Harmonic Motion
The mass of the block and the spring constant of a damped spring-mass system is 400 gm and 100 N/m respectively. If the damping constant is 10 kg/sec, then find the time taken for its amplitude of vibrations to drop to half of its initial value.
