Question 1
A particle moves along a straight line from a fixed point O. Its displacement, s metre, at t seconds after passing O is given by . Calculate
(a) the distance, in m, of the particle from the fixed point O when t=8,
(b) its velocity, in ms-1, when t=1,
(c) its acceleration, in ms-2, when t=3,
(d) the values of t, in seconds, when the particle stops momentarily.
