A constant horizontal pull of 8.70 N drags a box along a
horizontal floor through a distance of 17.3 m .
Part A: How much work does the pull do on the box? W = ?
J
Part B Suppose that the same pull is exerted at an angle above
the horizontal. If this pull now does 52.0 J of work on the box
while pulling it through the same distance, what angle does the
force make with the horizontal? Angle = ?
