A truck covers 40.0 m in 8.50 s while smoothly slowing down to a final speed of 2.80 m/s. (a) Find the truck's original speed. (b) Find it's acceleration.(adsbygoogle = window.adsbygoogle || []).push({});

I used the 2nd formula originally (X=VoT+1/2aT^2) but I wasn't getting anywhere. Can someone point me in the right direction on how to do this problem? Any help is appreciated. Thanks.
