(adsbygoogle = window.adsbygoogle || []).push({}); 1. A truck covers 50.0 m in 9.00 s while smoothly slowing down to final speed 2.40 m/s.

Find the trucks original speed.

Find its accleration.

2. Relevant equations

im using

x = v0*t + 1/2 *a*t2

and

v2 = v02 + 2*a*x

I believe this is what the question gives me.

Xo = 0

Xf = 50

Vo = ?

Vf = 2.4

a = ?

t = 9 secs

3. im positive that i have to use the two equations stated above. but both equations have accleration and Vo as unknown variables. i just need a hint on whats the best way to find accleration or Vo. I dont know if im clear what im saying but its the best way i can explain it. sorry.
