In order to obtain the acceleration
a(t) of the particle,
we determine the time derivative of its velocity vector
v(t).
ax(t)i +
ay(t)j
= a(t)
= dv(t)/dt
= dvx(t)/dt
i
+ dvy(t)/dt
j
= d(1.06)/dt
i
+ d(0.44)/dt
j
= 0i
+ 0j
= 0 cm/s2
or in column notation

We find that the particle has no acceleration (which we knew already
since it moves with constant velocity).
