What is the initial velocity of the apple when it is dropped?

• 15 m/s

• 0 m/s

• 5 m/s

• 10 m/s

What is the purpose of drawing a picture in the problem-solving process?

• To calculate the mass

• To measure the height of the tower

• To determine the color of the apple

• To visualize the problem

Which of the following is NOT a variable in the kinematic equations discussed?

• Final velocity

• Time

• Initial velocity

• Mass of the object

Why is the initial velocity squared considered zero in the calculation?

• Because the initial velocity is negative

• Because the apple is moving horizontally

• Because the initial velocity is zero

• Because the apple is thrown upwards

What is the acceleration due to gravity used in the calculations?

• 11.81 m/s²

What is the final velocity of the apple just before it hits the ground?

• -105 m/s

• -95 m/s

• -85 m/s

• -75 m/s

Which direction is the final velocity of the apple pointing?

• Diagonally

• Horizontally

• Downwards

• Upwards

What is the significance of the negative sign in the final velocity?

• It indicates the apple is moving sideways

• It indicates the apple is moving downwards

• It indicates the apple is stationary

• It indicates the apple is moving upwards
