ou have been talked into pulling two children on a sled in the snow. When you pull the rope tied to the sled, it makes an angle of 40° with the horizontal. The children have a combined mass of 45 kg and the sled has a mass of 5 kg. The coefficient of static friction is 0.20 and the coefficient of kinetic friction is 0.15. assuming you start from rest, what force of tension must you pull with to get the sled moving?
