Ben finds a bottomless pit in Nebraska. He throws a stone into it
downward at a 60 degree angle with an initial velocity equal to 12
m/s. What's the acceleration 9.8 seconds after the stone is
thrown? |

Bozo, the physicist, throws a pie at a velocity of 12 m/s. It
makes an angle of 30 degrees with the horizon as it leaves his
hand. How far will the pie travel before hitting a policeperson at
the same height as the pie was thrown? |

If a ball is throw with a velocity of 25 m/s at an angle of 37
degrees above the horizontal, what is its horizontal velocity
component? |

A ball is thrown at an original speed of 8.0 m/s and an angle of
35 degrees above the horizontal. What is the speed of the ball
when it returns to the same horizontal level? |

When adding two vectors, the resultant will be greatest when the
angle between the two vectors is ____________. |

Sir Winford fires a giant rock from a trebuchet at a 60 degree
angle with the horizontal and it lands 150 yards in front of him.
He then fires a second rock with a 25% more mass at an angle of 30
degrees and the same initial velocity as the first. What is the
second rock's range? |

A paratrooper fires his rifle straight down when flying in a plane
horizontally. When the bullet hits the ground, the plane will be
_______________. |

Bozo, the physicist, gets zapped with a Tesla coil as he stands on
top of his lab building. This causes him to jump over the edge at
a velocity of 5 m/s. The building is 3 meters high. As he jumps,
Bozo makes a 20 degree angle with the horizon. |

|
a) How high does he go? |
|
|
b) How long does it take to reach the top? |
|
|
c) What is the horizontal velocity at the top? |
|
|
d) How far does it travel horizontally before
hitting the ground? |
|
|
e) What is the x-velocity just before it hits
the ground? |
|
|
f) At what point in the Bozo's path is the
velocity highest? |
