**1. Homework Statement**

The velocity of an object, starting at the origin, and moving along the x-axis is given by

V(t)=(t-1)(t+1)^1/2. Find the time when the object will be at x=10/3. Units are not given. Since we are dealing with the x-axis I am using units as the measurement of distance and second as the measurement as time.

**3. The Attempt at a Solution**

My attempt to find t was to set 10/3 equal to my V(t) which I then got 13.842 seconds. Then to see if this is possibly a reasonable answer I substituted 13.842 in for t and found the velocity which was 3.593 units per second.

Im not really sure if I am approaching this problem correctly. I feel that what I did was a little too easy for second semester calculus. Thanks for your help everyone.
