An object is at rest at #(7 ,3 ,9 )# and constantly accelerates at a rate of #7/4 ms^-2# as it moves to point B. If point B is at #(2 ,5 ,8 )#, how long will it take for the object to reach point B? Assume that all coordinates are in meters.
First we find the distance between the points, which is
Find the distance between the points:
Now to find the time taken:
The initial velocity,
