Initial Velocity of the bus= 0m/s
Final Velocity of the bus= 72km/h or 20m/s
Time= 20 seconds
Acceleration= (v-u)/t, where u is initial velocity
v is final velocity and t is time.
(20-0)/20= 1m/s^2
Acceleration of the Bus= 1m/s^2
NOTE: If the velocities are given in any unit other m/s then, they need to converted to the same since, SI unit of velocity as well as acceleration are m/s and m/s^2, respectively.
HOPE THIS HELPS.
