Chapter 3, Problem 6P

At t = 0, a particle moving in the xy plane with constant acceleration has a velocity of ${\stackrel{\to }{v}}_i=(3.00\hat{i}-2.00\hat{j})\text{m/s}$ and is at the origin. At t = 3.00 s, the particle’s velocity is ${\stackrel{\to }{v}}_f=(9.00\hat{i}+7.00\hat{j})\text{m/s}$. Find (a) the acceleration of the particle and (b) its coordinates at any time t.
