TEST 2 Q 1 some ACADEMIC review questions to try

Define:
displacement, velocity, average velocity, average speed, acceleration.

Describe the
motion of an object that starts with:

Positive
velocity, positive acceleration

Positive
velocity, negative acceleration

Negative
velocity, positive acceleration

Negative
velocity, negative acceleration

When does an
object have an average velocity of zero?

A ball is rolled down a ramp.

Sketch the D-T and V-T graph.

Explain how to get the acceleration, using only a stopwatch and ruler. (T & D)

If the a is 1 m/s^{2},
what is the ball’s velocity after 5 seconds? What is its average velocity? How
much distance has it covered in that time? What was the distance traveled in
the 5^{th} second? (from 4 to 5)

--------------------------------------------

A ball is
thrown up in the air and caught at the point of release.

Sketch the D-T
and V-T graph.

Explain what
two pieces of information would help calculate the maximum height.

Explain what
would be different about the ball’s path, its maximum height, its graphs, and
its time and velocity if this were done on Jupiter (greater gravity).

A speeder going
at a constant speed passes a police car, who starts accelerating from 0 some
time later. Explain how to calculate when and where the cops catch the speeder,
and sketch a strobe motion dot image, D-T, and V-T graph for each.

TWO WORD
PROBLEMS TO TRY:

I start
traveling at 3 m/s and accelerate at the rate of 2 m/s^{2} up to a max
of 25 m/s.

A tiger is 70
meters behind me traveling a constant 20 m/s.

When I reach my
maximum speed of 25 m/s, will I be in front of, or behind the tiger?

I stand on a
cliff and jump up at 39.2 m/s. If I hit the valley below after 10 seconds, how
fast am I going? How high is the cliff? How high did I jump?

** How do you
calculate total distance for an object that has a starting velocity of zero,
accelerates, then stays the same speed, then slows down to zero again, if:

all
three parts of the journey are the same time.

WORD PROBLEMS
TO TRY:

A tennis ball
is released at the top of a 5-m ramp and rolls down .

The ball reaches
the end of the ramp in 5.0 s and rolls onto the floor. If the ball experiences
an

average
deacceleration of -0.25 m/s 2 as it rolls along the floor, how far from the end
of the ramp will the ball stop?

I start
traveling at 3 m/s and accelerate at the rate of 2 m/s^{2}, to a max of
25 m/s. I can only last 5 seconds at this top speed though….

A tiger is 50
meters behind me traveling a constant 20 m/s.

When I reach my
maximum speed of 25 m/s, will I be in front of, or behind the tiger?

Will I
eventually ever be ahead of him?

I stand on a
cliff and jump up at 39.2 m/s. If I hit the valley below after 10 seconds, how
fast am I going? How high is the cliff? How high did I jump?

If my friend
saw me and started running to catch me, with an acceleration of 3 m/s^{2},
how close would he have to be to the cliff to catch me?
