1. The person shown exerts a 1900 N force on the 80 kg block at an angle of 350 above the horizontal. The coefficients of friction are (0.6, 0.3). OO 2. A person pushes with a force of 400 N on the object on the left, which is in contact with the box on the right. The force is applied over 0.5 m. Make a complete model - in particular, create force diagrams for each box and for the earth and identify which forces are related by Newton's 3d Law. Also, calculate the work done by each force in this system. 400 N 40 kg 60 kg UK = 0.25 Uk = 0.4
