Problem
A vehicle is at position x0 metres at t=0. It first moves through a displacement d1=4a−3 metres and then through a second displacement d2=2a+5 metres, where a is a positive constant.
(i) Derive an expression for its final position xf in terms of x0 and a.
(ii) Calculate xf when x0=6m and a=3.
