A force F acting 30° from the horizontal is pulling the 1500 N-block along the horizontal plane. After traveling at a distance of 6 meters from rest, the force F is then removed. If F = 800 N, compute the velocity of the of the block after it has moved a total distance of 8.5 meters. Coeff. of friction is 0.20.
