A particle P of mass 2kg undergoes simple harmonic motion along the x-axis and is attracted towards the origin by a force who's magnitude is numerically equal to 8XN. If it is initially at rest at x=20m, and assuming a general solution of the form A cos wt + B sin wt, find the

I) Position of the particle at anytime
ii) the speed and velocity of the particle at anytime
iii)the magnitude,period and frequency of the vibration
