The oscillation of an object of on a frictionless surface is characterised by the following parameters: Amplitude = 5.0 cm. Maximum speed = 27.0 cm/s, Position at t= 0 is x(0) = +2.0 cm.initial velocity is to the left (i. e. x(0) <0), mass m = 0.20 kg. (a) Determine the force constant of the spring? (b) determine the angular frequency @ of this motion? (c) Calculate the period T of this motion? (d) If the position of the object is x(t) = A cos(wt + ), determine the phase constant, op? Be sure that your answer gives the correct sign for x(0). (e) Write down expressions for x(t) and x(t).
