suppose that we have a particle excuting S.H.M following the relation:
x = 0.1 sin(2pi/3 t - pi/4) m
find:
a) the amplitude, angular frequency, phase difference, T, f
b) if this motion describes a harmonic oscillator with a body (0.5kg) hang to it , then what is the force constant k?
c) if this motion describes a simple pendulum , then what is its length?
d)calculate the velocity and accelleration of the particle after t =2sec.
e) if two such waves are added togather, what is the resultant equation of motion for the composite waves?
