AP Physics C  Practice Test 3 Projectile Motion

    Assume magic land conditions on all problems unless stated otherwise. In other words there is no air resistance or friction.
1 ) 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?  1g
2 ) 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?  12.48 m
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? 20 m/s
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? 8.0 m/s
5 ) When adding two vectors, the resultant will be greatest when the angle between the two vectors is ____________. zero
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? 150 yards
7 ) A paratrooper fires his rifle straight down when flying in a plane horizontally. When the bullet hits the ground, the plane will be _______________.  Directly over the bullet
8 ) 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? 0.15 m above starting point
    b) How long does it take to reach the top? 0.17 sec
    c) What is the horizontal velocity at the top? 4.7 m/s
    d) How far does it travel horizontally before hitting the ground? 2.9 m
    e) What is the x-velocity just before it hits the ground? 4.7 m/s
    f) At what point in the Bozo's  path is the velocity highest? just before hitting the ground

Insultingly Stupid Movie Physics is one of the most humorous, entertaining, and readable physics books available, yet is filled with all kinds of useful content and clear explanations for high school, 1st semester college physics students, and film buffs.

It explains all 3 of Newton's laws, the 1st and 2nd laws of thermodynamics, momentum, energy, gravity, circular motion and a host of other topics all through the lens of Hollywood movies using Star Trek and numerous other films.

If you want to learn how to think physics and have a lot of fun in the process, this is the book for you!
