Two children, Raffi and John, sitting on sleds tied together with a massless rope, are being dragged across a frozen river by their playful Siberian husky Rex who is supplying a 112-N horizontal force. The coefficient of friction between the sleds and the ice is 0.07, the combined mass of Raffi and his sled is 43.0 kg, and the combined mass of John and his sled is 55.5 kg. (Assume Raffi is the child on the left and John is the child on the right.) What is the acceleration of the system? (magnitude only.) What is the tension FT  in the rope connecting the two sleds?

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:
