Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which of the following is NOT a characteristic of projectile motion?
Constant horizontal velocity
Constant vertical velocity
Parabolic trajectory
Affected only by gravity (ignoring air resistance)
2. At what point in a projectile's trajectory is its vertical velocity momentarily zero?
At launch
At landing
At the highest point of its trajectory
Never
3. The path followed by a projectile is called its .
4. In the absence of air resistance, the horizontal acceleration of a projectile is .
5. The acceleration due to gravity acts only in the direction.
6. Air resistance significantly affects the trajectory of a projectile.
True
False
7. The time it takes for a projectile to reach its maximum height is equal to the time it takes to fall from its maximum height back to its launch height.
True
False
8. A cannonball is fired horizontally from a cliff. Describe the motion of the cannonball in both the horizontal and vertical directions, ignoring air resistance.
9. Explain the effect of launch angle on the range and maximum height of a projectile.
10. A stone is thrown horizontally with a velocity of 15 m/s from the top of a 78.4 m high cliff.
a) How long does it take for the stone to reach the bottom of the cliff?
b) How far from the base of the cliff does the stone land?
c) What is the vertical velocity of the stone just before it hits the ground?
