A particle starts from rest at a fixed point O and moves along a straight line with velocity v . It is given that , where t is the time in seconds after the motion begins, and p and q are constants. The particle is momentarily at rest when t=1 second, and its displacement at that time is 2 meters to the left of point O.
[Assume motion to the right is positive]
(a) Calculate the value of p and q.
(b) By using the value of p and q obtained in (a), (i) find the initial acceleration
(ii) calculate the total distance travelled by the particles in the first 2 seconds.
