2. If the ball in Question 1 is traveling at a known horizontal velocity when it starts to fall, explain how you would calculate how far it will travel before it hits the ground. 3. A pair of computer-interfaced Photogates/Motion Detector can be used to accurately measure the time interval for an object to break the beam of one Photogate/Motion Detector and then another. If you wanted to know the velocity of the object, what additional information would you need? 4 - 2 Physics with Computers
