An object is at rest at #(8 ,3 ,3 )# and constantly accelerates at a rate of #7/4 ms^-2# as it moves to point B. If point B is at #(6 ,3 ,4 )#, how long will it take for the object to reach point B? Assume that all coordinates are in meters.
First step is to find the distance between the two points:
Second step is to find the time taken:
To find the distance between two points in 3D space we have:
Now to find the time taken, we can use:
Since the object is initially at rest, the
Note that I have used both
