1.)The velocity of a particle which moves along a linear reference axis is given by v = 2—4t + 5t^3/2, t is in seconds while v is in meters per second. Evaluate the position, velocity and acceleration when t = 3 seconds. Assume your own initial position and initial point in time. Further, set a variable for posi-
tion as you see fit.
2.)The displacement of a particle which moves along the x axis is given by x = (-2 + 3t)e^-0.5t, 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.
