1) Points A,O,B lie in that order on a straight line .A particle P is moving on the line with S.H.M of period 3s , amplitude 0.6m and centre O. Given that OA is 0.3 m and OB is 0.4 m , calculate the time taken by P to move directly from A to B.
2) Point O, A, B lie in that order on a straight line. A particle P is moving on the line with S.H.M of period 4 s, amplitude 0.5m and centre O. OA is 0.1m and OB is 0.3m . When t=0 P passes through B traveling in the direction OB. Calculate the time when P Reaches A.
