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.

**drwls**, Sunday, April 12, 2009 at 11:23pma) Calculate the change in x from t=1 to t=3 and divide by 2 s for athe anverage velcoity

b) Calculate dx/dt at t=1

velocity = dx/dt = e^t - (1/2)/t^1/2

c) Find out when dx/dt > 0 . That will be the answer. You may need to graph dx/dt

d) Solve for t when dx/dt = 0

Use that t in the x(t) equation.

These are exercises you should be able to do yourself. Someone will gladly critique your work.
