12.5 m
20.0
1. A heavy box is raised by sliding it 12.5 m along a plank oriented at 20.0 to the
horizontal as shown.
a. How high above the original position is it raised?
b. How far is it moved horizontally?
c. What is the displacement of the box in unit vector notation?
2. A room has dimensions 23 ft  5.0 ft  14 ft
as in the diagram. A fly starting in one
corner flies around, ending up at the
diagonally opposite corner.
a. What is the magnitude of its
displacement?
b. Could the length of its path be less than
this distance? Greater than this
distance? Equal to this distance?
c. Using the coordinate system in the
diagram, write this displacement in unit
vector notation.
