A heavy sled is being pulled by two people, as shown in the figure. The coefficient of static friction between the sled and the ground is µ, = 0.571, and the kinetic friction coefficient is = 0.419. The combined mass of the sled and its load is m = 321 kg. The ropes are separated by an angle ø = 25.0°, and they make an angle 0 = 29.7° with the horizontal. Assuming both ropes pull equally hard, what is the minimum rope tension required to get the sled moving? minimum rope tension: N If this rope tension is maintained after the sled starts moving, what is the sled's acceleration? acceleration: m/s?

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
