exploring creation with physics
make sure you understand these concepts by solving the following "on your ow
your own" problem.
on your own
2.00 x 10 meters down the stree
1.2 a mail carrier drives down a street delivering mail. she travels 3.00 x 102 met
in 332 seconds. she then turns around and heads back up the street, but because of the way
mailboxes are placed, she only needs to travel 208 meters in that direction, and that trin tak
2.30 x 10- seconds. what was her velocity as she traveled down the street? what was it as she
traveled up the street? what was her velocity for the entire trip?
now of course, equation (1.1) has more applications than the ones you have seen so far. stub
the next example and solve the "on your own" problem that follows in order to see how other types
of problems can be solved using this equation.
