Mrs. Steckel is pulling a 30 kg box full of textbooks with a rope across a rough surface. She is pulling so hard that the box is speeding up and has an acceleration of 4.0 m/s2. 1. Determine if the system is balanced or unbalanced, then draw a force diagram using on-by notation, construct an x/y table of equations, and write a net force equation for the crate ( 12 points). Force Diagram Fnet Equation Balanced or Unbalanced? 2. Calculate the normal force of the box (1 point). Show all your work and equations (1 point) Calculate the net force acting on the box (1 point). Show all your work and equations (1 point). 4. Calculate the value of the tension force if the ground exerts a 65 N frictional force opposing the motion (1 point). Show all your work and equations (1 point)
