Force on an Accelerating Car: Calculating the Net Force

[Wanting to Learn]

Hello, since this is a new topic in class I just want to check that I am doing the question correctly.
Given:
car mass = 710kg
starts from rest
v₀ = 0
travels 40.0m in 3.0s
d = 40.0m
t = 3.0s

Question:
What is the net force exerted on the car?
F = ___N

Work:
First I calculated acceleration:
d = v₀t + 0.5at²
40 = 0 + 0.5a3²
40 = 4.5a
a = 8.888 => 8.9

Then force:
F = m•a
F = 710•8.9
Answer:
F = 6319N

Is this correct? Thank you in advance.

Thank you. I included all the information which the template asks for; I just found it easier to to format as I did.
