Mechanics stuck on a sum on simple harmonic motion:help:
A particle P is moving on a straight line with S.H.M. of period pi/3 s. Its maximum speed is 5 m/s. Calculate the amplitude of the motion and the speed of P 0.2s after passing through the centre of oscillation.
T=2pi/w So w=6
5^2=6^2(a^2-0) so a=5/6 (matched with book)
The answer given in book is 1.81.
Somebody help. What did go wrong with this very simple sum?http://static.thestudentroom.co.uk/i...ilies/help.gif
