# An object is at rest at #(2 ,1 ,6 )# and constantly accelerates at a rate of #1/4 m/s^2# as it moves to point B. If point B is at #(3 ,4 ,7 )#, how long will it take for the object to reach point B? Assume that all coordinates are in meters.

##### 1 Answer

It will take the object

#### Explanation:

You can use the equation

where

The distance between the two points is

r = || (1,3,1) || =

Substitute

Round to however many decimal places are requested, or to significant figures, of which here there is one, so
