[b]1. An object moving with uniform acceleration has a velocity of 17.0 cm/s in the positive x direction when its x coordinate is 3.00 cm. If its x coordinate 2.60 s later is -5.00 cm, what is its acceleration?
x = x_0 + v_0 t + (1/2) a t^2
X = 5
Xo = 3
V = 17...
[b]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.
[b]2. Homework Equations
x = v0*t + 1/2 *a*t2
v2 = v02 + 2*a*x
I believe this is what the question gives me.
