A 6.53-kg block initially at rest is pulled to the right along a horizontal surface by a constant force of 125 N applied at an angle θ above the horizontal. The coefficient of kinetic friction between the block and the horizontal surface is 0.150. At what angle θ above the horizontal surface should the force be applied to achieve the largest possible speed after the block has moved 5.00 m to the right?
