I know this is the Precalculus Mathematics forum, but this is the kind of intro-level stuff that is taught in general high school mathematics classes before high school calculus, so I thought it would be better off here.
An object is moving in a straight line.
P is a point on the line.
Its acceleration, a ms–2 at a time t seconds after it leaves P, is given by
a(t) = 2 – 6t
When t = 0, the object is at point P and has a velocity of 4 ms–1.
How far is the object from P when t = 3?
a(t) = 2 – 6t
Honestly, I'm not really too sure to begin with this one. It's obvious enough that P is at the y-intercept, +2, and that the gradient of a(t) = 2 – 6t is 6, but I don't know where to go from here.
Any help would be much appreciated.
