Not given, which made me rethink my approach. Should have used x=vi(t)+(1/2) at2 to solve for acceleration and then use that value for vf=vi+at.

I used Δx/Δt to get vf with my initial time and displacement set as 0. 1000m/5s=200m/s. I calculated average acceleration using a=(vf-vi)/(tf-ti) initals values both at 0 (200m/s)/5s to get a=40m/s/s.

[Mentor's note: This thread was moved to the homework section from General Physics, so it doesn't use the template.] Going over a basic kinematics problem with the prompt stating vi=0, x=1000m and Δt=5 and vf and a need to be solved using average v and a. Calculated vf=200ms and a=40m/s/s. But...
