Question

Derive expression for the amplitude of forced of a body and explain the phenomenon of resonance

Answer 1

Answer:

x ( t ) = A cos ( ω t + φ ) . This is the generalized equation for SHM where t is the time measured in seconds, ω is the angular frequency with units of inverse seconds, A is the amplitude measured in meters or centimeters, and φ is the phase shift measured in radians.
