I Review Learning Goal: To use Newton's laws of motion to calculate forces and accelerations in the motion of a particle. Part B In 1687, Isaac Newton presented three basic laws that describe the motion of a particle: A crate sliding down a ramp reaches the bottom of the ramp and slides across a flat floor. At the instant shown, the crate has a speed of v = 7.90 m/s. The crate comes to a stop after a distance z = 21.5 m. (Figure 1) What is tk, the coefficient of kinetic friction between the crate and the floor? Express your answer numerically to three significant figures. View Available Hint(s) • 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, F. experiences an acceleration, a, that has the same direction as the force and a magnitude that is directly proportional to the force. • Third law: The mutual forces of action and reaction between two particles are equal, opposite, and collinear IVO AI U vec O O ? Newton's second law can be expressed as the formula known as the equation of motion: H = F=ma where F is the force, or sum of forces, acting on the particle; m is the mass of the particle: and a is the acceleration of the particle. Submit Part Two players hit an air hockey puck simultaneously. One player hits the puck with a force F = 4.65 N at an angle = 28.8°. The other player hits the puck with a force F. = 5.40 N at an angle o = 68.0. (Figure 2) If the puck has a mass m1 = 51.0 g, what is a, the acceleration of the puck, and y, the angle of the puck's motion? The friction between the puck and the table's surface is negligible.
