Question 3 An arrow is shot horizontally out across a field and falls short of the target. Which of the following statements is true for the arrow as it follows its trajectory until it lands on the ground? (2b4, DOK 2) The arrow's acceleration, horizontal velocity, and vertical velocity all remain constant. The arrow's vertical velocity and acceleration remain constant throughout the motion. Its horizontal velocity changes. O The arrow's vertical velocity increases as it falls. The acceleration and horizontal velocity remain constant throughout the trajectory. The arrow's acceleration increases which is why the velocity of the arrow is increasing. Question 4 A cannon fires horizontally off the top of a ship. If the cannon fires from a height of 24 m and the cannonball's velocity is 19 m/s. With these givens which equation would be used to find the time the cannonball is in the air? VF=Vi + at 2Ay t = g dx =Vxt You cannot calculate time in the air with these givens
