An object moving with uniform acceleration has a velocity of 15.0 cm/s in the positive x direction when its x coordinate is 3.00 cm. If its x coordinate 1.60 s later is -5.00 cm, what is its acceleration?

**Math**

a plane flies due north at 300 mi/h for 3 h then due west at 250 mi/h. If x represents the number of hours the plane is flying due west, determine for what values of x the plane will be more than 3700 mi from it's original point.
