1. A model rocket flies horizontally off the edge of the cliff at a velocity of 50.0 m/s. If the canyon below is 100.0 m
deep, how far from the edge of the cliff does the model rocket land?
a. 112 m c. 337 m
b. 225 m d. 400 m
2. What is the path of a projectile?
a. a wavy line
b. a parabola
c. a hyperbola
d. Projectiles do not follow a predictable path.
3. A stone is thrown at an angle of 30.0 above the horizontal from the top edge of a cliff with an initial speed of 12
m/s. A stopwatch measures the stone’s trajectory time from the top of the cliff to the bottom at 5.6 s. What is the height
of the cliff? (Disregard air resistance. g = 9.81 m/s 2 .)
a. 58 m c. 120 m
b. 150 m d. 180 m
4. A track star in the long jump goes into the jump at 12 m/s and launches herself at 20.0° above the horizontal. How
long is she in the air before returning to Earth? (g = 9.81 m/s 2 )
a. 0.42 s c. 1.5 s
b. 0.83 s d. 1.2 s
A D= All the same
B C
5. At which letter is the horizontal speed the greatest? ____ the least?_____
6. At which letter is the vertical speed the greatest? _____ the least? _____
7. At which letter is the vertical speed zero? _____
8. At which letter is the acceleration the greatest? _____ the least? _____
Consider the following situation:
Lee Key Faucet launched a clay duck into the air with a velocity of 20 m/s at an angle of 37 degrees. The clay duck is
not hit by the marksman shooting the rifle.
How would changing the following variables affect the a) time in flight, b) max height, c) range?
Double the Vi a) b) c)
Decrease the angle to 10 degrees a) b) c)
Double the mass of the duck a) b) c)
Increase the angle to 55 degrees a) b) c)
