Answer
x = 0
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 = 1 s we need to find x(1), or in other words, plug in 1 for t in the equation. This gives us:
$ x = 3(1) - 4(1)^2 + (1)^3 = 3 - 4(1) + 1 = 3-4+1 = 0 $
Therefore at t =1, the position of the object is x = 0
