2. The displacement of a particle which moves along the x axis is given by x = (-5 + 3t)^e-0.2t, consider x to be in feet and t in seconds. Plot the displacement, velocity and acceleration for the first 20 seconds of motion and determine, both graphically and by your established equation for acceleration, the time at which acceleration is 0.
