Read each question carefully and provide your answer in the space provided. Show all your work for calculation problems.
1. Which of the following statements is true regarding the horizontal velocity of a projectile?
It constantly increases due to gravity.
It constantly decreases due to air resistance.
It remains constant in the absence of air resistance.
It is zero at the peak of the trajectory.
2. A ball is thrown horizontally from the top of a cliff. What is the direction of its acceleration just after it leaves the cliff?
Horizontal
Vertical, upwards
Vertical, downwards
Both horizontal and vertical
1. Projectile motion is the motion of an object thrown or projected into the air, subject to only the acceleration of .
2. The path followed by a projectile is called its .
3. In the absence of air resistance, the horizontal and vertical components of projectile motion are of each other.
1. The vertical velocity of a projectile is constant throughout its flight.
True
False
2. At the maximum height of its trajectory, a projectile's vertical velocity is zero.
True
False
1. A stone is thrown horizontally from the top of a 20 m high building with an initial speed of 15 m/s. Calculate the time it takes for the stone to hit the ground. (Ignore air resistance, g = 9.8 m/s²)
2. Referring to the previous question, what is the horizontal distance the stone travels before hitting the ground?
Observe the image below showing projectile motion. Describe the forces acting on the object at points A, B, and C.
