					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)
Answers to Quiz:
a)   Draw picture and label all initial and final conditions
b)   How long it will take to hit the ground: .4285s
c)   How far the ball will land relative to the release point: 3.4m
d)   How fast it is moving when it hits the ground: 9.035m/s
