- Use 3 decimal places The 250-N block rests upon a level plane for which fk = 0.2. It is pulled by force P = 100N inclined at 20o with the horizontal. 1. If the 100-N pull is then removed, find the distance the block will travel. 2. Find the velocity of the block after it moves 20m starting from rest.Link ABC in the figure below has wheels at point A and B which remain in contact on the horizontal and vertical surfaces.
