SOLUTION: Jacob and Isaac pull firewood on a sled with a mass of 60kg to the right across a snow covered field. Jacob pulls with a force of 30N and Isaac pulls with a force of 20N and there

Question 1007677: Jacob and Isaac pull firewood on a sled with a mass of 60kg to the right across a snow covered field. Jacob pulls with a force of 30N and Isaac pulls with a force of 20N and there is a force of friction of 15N.
1. What is the net force acting on the sled?
2. What is the acceleration of the sled?
Answer by fractalier(6550) (Show Source): You can put this solution on YOUR website!
1) The net force is 30N + 20N - 15N = 35N to the right...friction almost always works in opposition to the motion...
2) Newton's Second Law gives a = F/m = 35N / 60kg = .583 m/s^2
