Answer:

Explanation:

Yes i will agree with the driver and wear safety belts because according to the newtons first law of motion it states that " every body continues to be in its state of rest or uniform motion in a straight line unless it is compledd by some external effort to change that state".So according to this if a bus moves our body also moves beacuse effort is applied when in the moving bus.

acceleration=final velocity - initial velocity/time taken

=(20-10 )/20

=10/20

=0.5 m/s
