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. Homework 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. I am 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 what's the best way to find accleration or Vo. I don't know if I am clear what I am saying but its the best way i can explain it. sorry.
