Question:
A particle starts from rest at a fixed-point O and moves in a straight lie towards a point A. The velocity, v ms-1, of the particle, t seconds after leaving O, is given by v = 8 – 8e-2t.
a. Find the acceleration of the particle when t = ln 5.
b. Given that the particle reaches A when t = 2 find the distance OA. Give your answer correct to 3 sf.
