An object is at rest at #(8 ,4 ,2 )# and constantly accelerates at a rate of #4/3 m/s# as it moves to point B. If point B is at #(3 ,1 ,6 )#, how long will it take for the object to reach point B? Assume that all coordinates are in meters.

Explanation:
let initial point A be (8,4,2) and final point B be (3,1,6)
by distance formula,
=
So, s =
also,
as object is at rest and starts constantly accelerating,
initial velocity ' u' = 0
By using equation,
s = ut +
as u = 0, s =
7 =
t =
