Projectile MotionYou have probably watched a ball roll off a table and strike the floor. What determines where it will land?Could you predictwhere it will land? In this experiment, you will roll a ball down a ramp and determine Figure 1 objectives Measure the velocity of a ball using a Photogate. Apply concepts from two-dimensional kinematics to predict the impact point of a ball in projectile motion. Take into account trial-to-trial variations in the velocity measurement when calculating the impact point. Materials 1
LabQuest plumb bob LabQuest App ramp 2 Vernier Photogates ring stand target right-angle clamp ball (1 to 5 cm diameter) meter stick or metric measuring tape masking tape Preliminary questions 1. If you were to drop a ball, releasing it from rest, what information would be needed to predict howmuch time it would take for the ball to hit the floor? What assumptions must you make? 2. If the ball in Question 1 is traveling at a known horizontal velocity when it starts to fall, explain howyou would calculate how far it will travel horizontally before it hits the ground.3. When an object passes through a Photogate, it blocks the passage of light from one side to the other.The interface can accurately measure the duration of time that a gate is blocked. If you wanted to know thevelocity of the object, what additional information would you need?
