Solve the following problems completely: Show your complete solution. Sketch the graph. 1. A 450N wooden box is pushed across a horizontal floor with a force of 501b. The coefcient of sliding friction, U = 0.35. a. Find the work done in pushing the box 49.20 feet. b. How much work went into overcoming friction? c. How much work went into accelerating the box? If Sir Fabro lifts a 20N box 2.0kg to a table that is 5 meters high, A. How much gravitational potential energy [P.E. grav.) did Sir Fabro give the box? B. If Sir Fabro pushes the box oil" the table, how fast would it be moving right before it hits the ground? C. What is the Kinetic Energy just before the box hits the ground? A child pulls a 6kg box a distance of 12m along a horizontal surface at a constant speed. What work does the child do on the box if the coefcient of kinetic friction is 0.20 and the cord makes an Angle of 45" with the horizontal
