(ii) Describe how the acceleration of the train at time t = 100 s differs from the acceleration
at time t = 20 s.
                                             
                                          
                                          
                                        
											 
											Explanation:
Acceleration is the rate of change of velocity with time. When acceleration increases a body moves a faster velocity.
A vehicle at time 100s will have a faster velocity compared to one at t = 20s
