The magnitude of the acceleration of the car is determined as 1.11 m/s².
Acceleration of the train
The acceleration of the train is determined as the rate of change of velocity with time.
The magnitude of the acceleration of the car is calculated as follows;
a = v/t
a = 50/45
a = 1.11 m/s²
Thus, the magnitude of the acceleration of the car is determined as 1.11 m/s².
