rk 1 Part 5: x(t) and velocity lo submitted Jan 31 at 1:26am empt took 53 minutes. A particle moves along the x-axis. Its position as a function of time is given by e (t)-3t2t The following questions refer to that situation. Only consider times t greater than or equal to zero (no negative values of t). Note: Some of the questions ask about the maximum velocity attained, or the maximum x-coordinate, etc. Hint: use calculus! A very important application of the derivative is finding the maxima and minima of functions. 1/1 pts Question 1 At time t 0 is the particle moving in the positive x-direction, the negative x-direction, or is it
