A Free-Fall Problem That You Must Split Into Two Parts

The video tutorial covers solving a classic free fall problem using uniformly accelerated motion (UAM) equations. It begins with an introduction to the problem, followed by reading and translating the problem statement into known variables. The tutorial then calculates the initial velocity and splits the problem into two parts for detailed analysis. The maximum height reached by the ball is calculated, and an alternative solution is discussed. The session concludes with a review of the entire process.

What is the initial height from which the ball is thrown?

• 124 meters

• 1.24 meters

• 0.124 meters

• 12.4 meters

How long does the ball stay in the air before hitting the ground?

• 3.14 seconds

• 0.14 seconds

• 2.14 seconds

• 1.14 seconds

Which of the following is the correct acceleration due to gravity used in the problem?

• -9.81 m/s²

• 0 m/s²

• 19.62 m/s²

• 9.81 m/s²

What is the initial velocity of the ball calculated using the UAM equations?

• 6.374 m/s

• 4.504 m/s

• 5.134 m/s

• 3.503 m/s

At the maximum height, what is the velocity of the ball?

• 0 m/s

• 4.504 m/s

• 9.81 m/s

• -9.81 m/s

Why is it necessary to split the problem into two parts?

• To find the maximum height

• To handle different accelerations

• To account for different velocities

• To simplify calculations

What is the displacement in the Y direction during the ascent?

• 3.033 meters

• 0.273 meters

• 2.273 meters

• 1.033 meters

How is the maximum height above the ground calculated?

• By adding initial height and total displacement

• By subtracting initial height from total displacement

• By multiplying initial height and total displacement

• By dividing initial height by total displacement

What alternative method could be used to solve the problem?

• Using a different initial height

• Solving for final velocity of the total event

• Ignoring the acceleration

• Using only one UAM equation

What is the final maximum height reached by the ball?

• 1.24 meters

• 2.27 meters

• 4.27 meters

• 3.27 meters
