An object is at rest at #(2 ,9 ,5 )# and constantly accelerates at a rate of #1/6 m/s# as it moves to point B. If point B is at #(6 ,2 ,7 )#, how long will it take for the object to reach point B? Assume that all coordinates are in meters.
Let point start be
Let point end be
Let direct distance between
Then by using Pythagoras we have:
Using the standard form equation for distance
