Answer to Question #72634 in Physics for man

Question

The amplitude of an oscillator is 8 cm and it completes 100 oscillations in 80s.
i) Calculate its time period and angular frequency. ii) If the initial phase is π/4, write
expressions for its displacement and velocity. iii) Calculate the values of maximum
velocity and acceleration.
ii0 body of mass 0.15 kg executes SHM described by the equation
x(t) = 2sin(πt + π )4/
where x is in meters and t is in seconds. i) Determine the amplitude and time period
of the oscillation. ii) Calculate the initial values of displacement and velocity.
iii) Calculate the values of time when the energy of the oscillator is purely kinetic
