An automobile with four wheel drive has mass of 1000kg. Its weight is evenly distrubuted among the four wheels, whos coefficient of static frictin with the road is 0.80. If the car starts from rest and the road is horizontal calculate the maximum acceleration it can attain without spinning its wheels.(adsbygoogle = window.adsbygoogle || []).push({});

I did:

f = mumg

f = .8(1000)(9.8)

f = 7850

F=ma

7840=1000a

a= 7.84m/s2

Is this correct? If not, where did I go wrong? Thanks.
