the acceleration is the rate of change of velocity, so acceleration is the derivative of velocity\[a=\frac{dv}{dt}=(2\pi -5)-\pi \cos \pi t\]

to find the minimum acceleration of the particle, looking at 0≤t≤3 see that when t =0, the acceleration is at a minimum. so substitute t=0 in the equation of a
