A box of books is initially at rest a distance D = 0.367 m from the end of a wooden board. The coefficient of static friction between the box and the board is µs = 0.379, and the coefficient of kinetic friction is µk = 0.303. The angle of the board is increased slowly, until the box just begins to slide; then the board is held at this angle. Find the speed of the box as it reaches the end of the board.
