a) what is the car's acceleration?

b) How far will the car travel during the third second?

For a) I used v= v_0 +at

6=0 a*1 so a= 6m/s^2

For b) I used d=d_0 +v_0t + 1/2 at^2

=0 +0(3) + 1/2 (6)(3)^2

= 1/2(6)(9)

=27 m

Did I work out this problem correctly? Thanks in advance for your help.

b, find how far it went in two seconds, then in three seconds, and subtract to find how far in the third second.
