Answer
x = -2
Work Step by Step
The position is given by the equation $ x = 3t - 4t^2 + t^3 $ where x is in meters and t is in seconds
To find the position at t = 2 s we need to find x(2), or in other words, plug in 2 for t in the equation. This gives us:
$ x = 3(2) - 4*(2)^2 + (2)^3 = 6 - 4*4 + 8 = 6-16+8 = -2 $ Therefore x = -2
