Assume magic land conditions on all problems
unless stated otherwise. In other words there is no air resistance
or friction.

) 
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? 
3 
) 
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? 
4 
) 
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? 
5 
) 
When adding two vectors, the resultant will be greatest when the
angle between the two vectors is ____________. 
6 
) 
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? 
7 
) 
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 xvelocity just before it hits
the ground? 


f) At what point in the Bozo's path is the
velocity highest?
