initial velocity of the car given as

final velocity is given as

as we know that

now we can convert final speed into m/s

now acceleration is rate of change in velocity



so the acceleration of the car is 3 m/s^2
Answer:
4m
Explanation:
you divide 20m/s by 5 seconds
A=f/m
A=900/425
A=2.18
To determine acceleration you divide the force by the mass.
