- A cubic centimeter in a typical cumulus cloud contains
50 to 500 water droplets, which have a typical radius of
10 microns. (a) How many cubic meters of water are in a
cylindrical cumulus cloud of height 3.0km and radius 1.0km?

- Under what conditions is the magnitude of the vector sum
\( \overrightarrow{A}+
\overrightarrow{B} \) equal to the sum of the magnitude of the vectors?
- You walk 1.57km north, then turn and walk 0.846km east. Find
- the magnitude of your displacement vector and
- its direction, expressed as an angle relative to the northward direction.
-
Find the magnitude of the vector \(37m\) \(\hat{i}+ 15m\) \(\hat{j} \) and
determine its angle to the +x-axis.
-
A car drives north at 40mi/hr for 10min, then turns east and goes
5.0mi at 60mi/hr. Finally, it goes exactly southwest (half-way
between south and west) at 30mi/hr for 6.0min. Determine the car's
displacement.
- A hockey puck glides across the ice at 27.7m/s when a player
whacks it with her hockey stick, giving it an acceleration of
\(448m/s^2\) at \(75.0^o\) to its original direction. If the
acceleration lasts 41.3ms, what is the magnitude of the puck's
displacement during this time? (note that there is a related example
question in the textbook).
- A particle leaves the origin with its initial velocity given
by \(\overrightarrow{v_o}=11m/s \hat{i}+14m/s \hat{j}\),
undergoing constant acceleration
\(\overrightarrow{a}=-1.2m/s^2\hat{i}+0.26m/s^2\hat(j)\).
- When does the particle cross the y-axis?
- What is its y-coordinate at that time?
- How fast is it moving and in what direction (again when it
crosses the y-axis)?
- Using the data in
this table use a
spreadsheet to calculate and graph the position, velocity, and
acceleration of the object. The first velocity will be for the
time 0.05s (you will have 11 of them) and the first
acceleration will be at 0.10s (you will have 10 of
them). On the appropriate graph please circle the first
position, first velocity and first acceleration.

a speed of 11 m/s.
- How long does it take the shingle to reach the ground?
- How far does it move horizontally?

magnitude of the acceleration of its tip.
- A basketball player is 15 ft horizontally from the center of the
basket, which is 10 ft off the ground. At what angle should the
player aim the ball from a height of 8.2ft with a speed of 26 ft/s
to make it into the basket?

2.5m above the board and then enters the water 2.8m horizontally

A 12N horizontal force pushes a block with mass 0.5kg against a
vertical wall. The coefficient of static friction between
the wall and the block is 0.60 and the coefficient of
kinetic friction is 0.4. Assume that the block is not
moving initially. Will the block move?
