Dear student
 
acceleration will be zero
 
As acceleration is defined as the change in velocity with respect to time. but here velocity is constant hence no change. So acceleration is constant

We do acceleration as v/t but its actually change in velocity with resect to time. 
So, a = dv/dt.
But here dv =0 so a =0 as v is constant.
