Question 3
A particle moves along a straight line from a fixed point O for t seconds with an initial velocity of 8ms-1. The acceleration, a ms-2, of the particle t seconds after leaving O is given by . Calculate
[Assume motion to the right is positive]
(a) the velocity, in ms-1, of the particle when t=2,
(b) the displacement, in m, of the particle from O when t=5.
