What is the network done on the car during the time interval?

Mass = 75,000kg

Vi = 0

vf = 111.11m/s^2

t = 2.5s

∆x = 138.8875m

2. Relevant equations

W= F∆X

∆KE = (1/2)(m)(v)^2

W = ∆KE

3. The attempt at a solution

∆KE = 1/2(75000kg)(111.11m/s)^2

∆KE = 463953703.8j

And since W=∆KE

W = 463953703.8j

Is this right? I am wondering if I am missing gravity and kinetic friction somewhere?

Thanks
