# An object is at rest at #(5 ,1 ,1 )# and constantly accelerates at a rate of #2/5 m/s# as it moves to point B. If point B is at #(6 ,9 ,7 )#, how long will it take for the object to reach point B? Assume that all coordinates are in meters.

#### Explanation:

I am going to assume that there is a small typographical error in the units of the acceleration and it is

The distance, d, from Point

The equation for distance traveled under constant acceleration is:

Substitute

But negative time does not make sense, therefore, make it only positive:
