A particle moves along a straight line and passes through a fixed point O . It’s acceleration, a m s−2 , is given by a=2t−6 , where t is the time, in seconds, after passing through O . The initial velocity of the particle is 8 m s−1 . Find [Assume motion
a) the minimum velocity of the particle in ms-1
b)the value k if the particle always moves to the right after k seconds
c)the total distance, in m , travelled by the particle in the first 4 seconds.
