A bus is travelling along a straight road. The bus and the driver have a combined mass of 16000kg when there are no passengers in it. The bus has 73 passengers. The average mass of each of the passengers is 65kg. The fully loaded bus accelerates uniformly from rest to a speed of 14m/s. The time taken to reach a speed of 14m/s is 20s. Calculate the resultant force on the bus during the acceleration.
