### Learning Goal:In 1687, Isaac Newton presented three basic laws that describe the motion of a particle:#### First Law:A particle originally at rest, or moving in a straight line with a constant velocity, will remain in this state provided that the particle is not subjected to an unbalanced force.#### Second Law:A particle acted upon by an unbalanced force, \( \mathbf{F} \), experiences an acceleration, \( \mathbf{a} \), that has the same direction as the force and a magnitude that is directly proportional to the force.### FigureThe provided diagram illustrates the motion of a particle, specifically a box on a horizontal surface. The box is depicted moving to the right with a velocity denoted as \( \mathbf{v} \). There is a horizontal arrow pointing to the right indicating the direction of the velocity. Additionally, there is a distance labeled \( \mathbf{d} \) signifying the displacement the box undergoes along the horizontal plane. The diagram helps contextualize Newton's laws by visually representing a scenario where the motion of the particle (box) could be analyzed according to the stated principles. ### Physics Problem Exercises#### Part BA crate sliding down a ramp reaches the bottom of the ramp and slides across a flat floor.
