The position of a particle moving on the x-axis at time t>0 seconds is: x(t)= e^t - t^1/2.

a) Find the average velocity of hte particel over the interval [1,3].

b) In what direction and how fast is the particle moving at t= 1 seconds?

c) For what values of t is the particle moving to the right?

d) Find the postition of the particle when its velocity is 0.
