For this, drawing a sketch of the graph of velocity against time helps. To do this, find the velocity when t=0, and then find the times when the velocity is zero. Also find the time when acceleration is zero.

When is a particle speeding up
A particle is speeding up when the velocity and acceleration are in the same direction (have the same sign).
For this, drawing a sketch of the graph of velocity against time helps. To do this, find the velocity when t=0, and then find the times when the velocity is zero. Also find the time when acceleration is zero.
