What is the speed of an object that travels from #(4,-7,1) # to #(-1,9,3) # over #6 s#?
Well, first we need to find the displacement of the object.
The initial point is
So, to find the least displacement, we use the formula
Taking the initial points as that of
Now, the total time taken for this transit is
So, the velocity of the object in this transit would be
