```					Projectile Motion Problems:

1) A car runs off a 30m cliff at 50m/s. Find how
long it will take it to hit the ground and where it
will land relative to the cliff.
a)   How long it will take to hit the ground (2.47s)
b)   How far the bomb will land relative to the release point.
(123.7m)
c)   How fast it is moving when it hits the ground. (52.318m/s)
2) A plane is flying horizontally with a speed of
340 m/s at a height of 7200m. If the plane
drops a bomb, find the following:
a)     How long it will take to hit the ground (38.3 s)
b)     How far the bomb will land relative to the release point.
(13,033 m)
c)     How fast it is moving when it hits the ground.
(506.4 m/s)
3) A ball is clocked through a speed trap going 2
meters in 1.5 seconds. After being clocked, the
ball rolls off a table 1 meter high. Find the
following:
a)   How long it will take to hit the ground (.4517s)
b)   How far the ball will land relative to the release point.
(.6m)
c)   How fast it is moving when it hits the ground. (4.62m/s)
4)    A ball is clocked through a speed trap going 2
meters in .5 seconds. After being clocked, the
ball rolls off a 1 meter high table. Find the
following:
a)   How long it will take to hit the ground (.4517s)
b)   How far the ball will land relative to the release point.
(1.806m)
c)   How fast it is moving when it hits the ground (5.967m/s)
Physics Warm-Up
Superman is clocked through a speed trap going
30 meters in 2 seconds. After being clocked, he
trips and falls and rolls off a 10 meters high cliff
into a fresh batch of Jell-O. Find the following:

a)   Draw picture and label all initial and final conditions (5pts)
b)   How long it will take to hit the ground (5pts)
c)   How far the ball will land relative to the release point (5pts)
d)   How fast it is moving when it hits the ground (+5pts)
Projectile Motion Quiz:
An Irish gang runs a Scottish car off the Mexico
Baja Cliffs such that as it goes over the cliff, Mc
Heisenberg clocks it passing though 10 meters in 2
seconds . If the cliff is 200 meters high find the
following:

a)   Draw picture and label all initial and final conditions:
(5pts)
b)   Using the speed trap calculation, find the initial speed of
the car leaving the cliff. (5pts)
c)   How long it will take to hit the ground (5pts)
d)   How far the ball will land relative to the release point
(5pts)
e)   How fast it is moving when it hits the ground (+5pts)
