Anna Laura rides her bike. First she travels 3.5 km due east,
then she takes a left
turn and travels 2.5 km due north. Draw a graph illustrating the
motion; be sure to
choose a valid coordinate system and indicate the length scale of
your axes. Draw
the displacement vector x. Write the vector x include the magnitude
and the
direction; the direction can be an angle relative to one of your
axes.

When Susan rides her bike, the distance that she travels varies directly with the amount of time she is biking. Suppose she bikes 50 miles in 2.5 hours. At this rate, how many hours would it take her to bike 80 miles?

A: A bird watcher meanders through the woods, walking 0.30 km
due east, 0.80 km due south, and 2.30 km in a direction 45.0° north
of west. The time required for this trip is 4.00 h.
(a) Determine the magnitude and direction (relative to due west)
of the bird watcher's displacement. Use kilometers and hours for
distance and time, respectively.
(b) Determine the magnitude and direction (relative to due west) of
the bird watcher's average velocity.

1. Rachael runs 2 km to her bus stop, and then rides 4.5 km to
school. On average, the bus is 45 km/h faster than Rachael’s
average running speed. If the entire trip takes 25 min, how fast
does Rachael run?

A fishing boat leaves a dock at 2:00pm and travels due east at a
speed of 20km/h. Another boat has been heading due north at 15 km/h
and reaches the same dock at 3:00pm. At what time were the two
boats closest together?

Problem #3:
A particle travels across a at surface, moving due east for 4
m, then due north for 9 m, and then returns to the origin. A force
field acts on the particle, given by
F(x, y) =
sin(x2 +
y2) i + ln(6 +
xy) j
Find the work done on the particle by F.

A plane with a speed of 800.0 km/hr due east passes directly
above a train traveling due southeast at 100.0 km/hr on a straight
level road. The altitude of the aircraft is 10.0 km. How fast is
the distance between the plane and the train increasing 45 s after
the aircraft passes directly above the train?

A bicyclist rides on a North-South trail from her home to work.
She starts at home and rides due North for 22 minutes with a
velocity of 7.2 m/s. She gets tired, so she slows down and rides
for 36 minutes due North with a velocity of 5.1 m/s. Suddenly, she
realizes that she missed her destination, frantically turns around,
and rides due South for 8.0 minutes with a velocity of 10.1 m/s
before reaching work.
