# 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** = **7m approx**

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 =
