The amount of force (to a point) while pulling the car up the hill at an increasing angle. The work that was done .
Match the 'Example' to the appropriate classifciation:
force directly caused the displacement
there was zero displacement
vertical displacement was 4m, the horizontal force was 20N
the item sits on the shelf with 40J of Potential Energy
there was no force to cause the dispalcement
Work Was Done
No Work Was Done
Calculate the work done by a 40-N force (directed at a 20° angle to the vertical) to move a 5-kilogram box a horizontal distance of 500 cm across a rough floor at a constant speed of 0.7 m/s. (Make sure you show your work for partial credit!)
