What is the total flight time of the arrow in the problem?

• 9.81 seconds

• 3.25 seconds

• 12 seconds

• 6.5 seconds

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

• 10 m/s²

• 11 m/s²

• 9.81 m/s²

• 8.9 m/s²

Why is the final velocity at the maximum height considered to be zero?

• Because the arrow is still moving upwards

• Because the arrow has reached its maximum speed

• Because the arrow momentarily stops before descending

• Because the arrow is accelerating

What is the time taken for the arrow to reach its maximum height?

• 6.5 seconds

• 9.75 seconds

• 3.25 seconds

• 1.5 seconds

Which kinematic equation is used to solve for the initial velocity?

• Equation with final velocity, time, and acceleration

• Equation with change in position

• Equation with only initial velocity

• Equation with only time and acceleration

What is the initial velocity required for the arrow to achieve a total flight time of 6.5 seconds?

• 15.95 m/s

• 31.9 m/s

• 45.5 m/s

• 60 m/s

Why is the initial velocity considered positive in this problem?

• Because the arrow is moving downwards

• Because the arrow is moving upwards

• Because the arrow is moving horizontally

• Because the arrow is stationary

What is the significance of dividing the total time by two in this problem?

• To find the average speed

• To find the time for the upward path

• To find the total distance traveled

• To find the time for the downward path

What happens to the velocity of the arrow at the top of its path?
