Acceleration of a body is defined as rate of chance in velocity with respect to time and its S.I. Units are 
/ or 
Magnitude of average acceleration of a body = (final speed - initial speed)/time interval = 
where, final speed =v= 11 m/s; initial speed = u = 6 m/s; and time interval = t = 3 s
Hence acceleration = 
= 
=
