Q1: Sketch
the path of this imaginary coin, including a definition of coordinates.
Label the following points on your sketch.
Point 1 
The coin has just left your hand moving upwards 
Point 2 
The coin is about 1/4 of the way up to the top
of its path 
Point 3 
The coin is about 3/4 of the way up
to the top of its path 
Point 4 
The coin is exactly at its maximum height of about
2.5m 
Point 5 
The coin is about 1/4 of the way down from the
top of its path 
Point 6 
The coin is about 3/4 of the way down from the
top of its path 
Point 7 
The coin is just above your hand and is about
to be caught 
Q2: Assume
upwards displacement is positive. Indicate the following points
on your sketches. (In some cases there may be none, or more than
one correct point. When this is so, explain in words.)
Point A 
Maximum displacement of the coin 
Point B 
Zero displacement of the coin 
Point C 
Minimum displacement of the coin 
Point D 
Maximum velocity of the coin 
Point E 
Zero velocity of the coin 
Point F 
Minimum velocity of the coin 
Point G 
Maximum acceleration of the coin 
Point H 
Zero acceleration of the coin 
Point I 
Minimum acceleration of the coin 
Q3: From
your observations in Q2, prepare three sketch graphs: position vs.
t, velocity vs. t and acceleration vs. t for one complete toss of
the coin. Align the graphs in a colunm so that you can readily read
the x,v and a values for the same time.
Q4: In
your own words, describe how the position of the coin changes with
respect to time during the toss.
The zero frame of reference is your hand going up in the positive
direction. The distance increases until it reaches a maximum height,
then the distance decreases until it reaches your hand at zero.
Q5: In
your own words, describe how the velocity of the coin changes with
resect to time during the toss.
The positive velocity occurs the instant the coin leaves our
hand. It immediately begins slowing up until its upward velocity
becomes zero at the maximum height. At this instant it begins to
fall and its velocity increase in a negative direction. The velocity
reaches its maximum negative value the instant before it touches
your hand.
Q6: In
your own words, desribe how the acceleration of the coin changes
with respect to time during the toss.
The acceleration never changes, its direction is downward at
9.8m/s
