Name: _________________________ Per: ____
Super Chef Lisa tosses a chicken to Super Chef Linda. The images of the chicken are shown at
exactly one-second intervals throughout its trajectory. The chefs are exactly 60 meters apart.
vy = _________
vx = _________
vy = _________
vx = _________
vx = _________
vy = _________
vy = _________
vx = _________
vx = _________
vy = _________
vy = _________
vx = _________
vx = _________
vy = _________
60 meters
1. How many seconds did it take the chicken to reach the top of its trajectory?
___________
2. How many total seconds was the chicken in the air?
___________
3. If the chefs were 60 meters apart, what must have been the horizontal speed
of the chicken throughout its trajectory?
___________
4. What must be the vertical speed of the chicken at the top of its trajectory?
___________
5. Based on the amount of time it took the chicken to reach the top of its trajectory ___________
what must have been the vertical speed of the chicken when Chef Lisa tossed it?
6. Based on all the information above, fill in the vertical and horizontal speeds of the chicken at
each one second interval in its trajectory.
7. How high must the chicken have been when it reached its peak (d= ½ at2)?
___________
Projectile Motion
Name: ___________________________
Physics 1
Period: ____
1 m/s
1. A coin rolls off of a table with a speed of 1 m/s. Assume the table top is
0.5 m off the ground. At the moment the coin leaves the table, its…
a. …horizontal velocity is: ________
…vertical velocity is: ________
0.5
m
2. So, when we analyze the motion of the coin as it falls we can think about it in the following
way:
a. Horizontally, we can imagine the coin is moving with a _____________________ of ________.
b. The reason we can assume this is because there are ___________________ acting in the
horizontal direction, and therefore there is nothing to change its horizontal velocity.
c. Vertically, we can imagine the coin is in a state of ______________________, and because it
leaves the table with no vertical velocity it is as though it was dropped ________________.
d. The reason we can assume this is because the force of ______________________ is acting on
the coin, pulling it down in the __________________ direction. This means that the coin will
________________ with a __________________________________ of ____________.
3. To determine where the coin will land on the floor, all we need to do is determine the
_________________ the coin travels in the _________________ direction during the
___________________ that it takes it to ___________ to the ground.
a. Vertical: We must first solve for the _____________ it takes the coin to hit the ground. To do
this, we can completely ignore the horizontal part of its motion and just worry about how it
____________. We know that in the vertical direction it starts from __________ and must fall
a distance of _________ at a rate of ___________. To do this, we can use the equation:
____________. So, now lets solve for time:
time in the air = __________
b. Horizontal: Now that we know how long it was in the air, we can figure out the
_________________ it travels across the ground during that _______________. We can do this
because we know that in the _________________ direction it is traveling with a
_____________________ of ________. Thus, we can use the equation ____________ to solve
for the distance. So, now lets solve for distance:
distance across the ground = _________
