A block has a mass  1989  grams and is setting on a flat, frictionless surface.  The block is pushed along until it has a speed of  3.31 m/s.  That force is removed, and then a short time later another force pulls upon the block via a massless rope angled at  26.6 degrees above the horizontal as shown below.  The force is steady at   16.63  mN and acts for   33.3 seconds.  So, what is the final speed of this block after this process? a)12.7 m/s b) 3.56 m/s c) 1.8 m/s d) 1.9 m/s e) 7.1 m/s
