Unformatted text preview: 2 . Let the motion progress for 6 seconds to find the final components. Show all your work/reasoning. 2) The initial velocity is 20m/s directed 40 clockwise from north. The acceleration is 6.0m/s 2 directed due west. Let the motion progress for 6 seconds to find the final components. Show all your work/reasoning. At what instant in time is the object moving due north? What is its speed then? Moving due North means the velocity vector points exactly north....
