Materials: ramp, ball, metre stick, stand, tape, landing platform. You're not to use ANYTHING other than these items. Procedure: You're on your own to figure this out. This is an exercise in problem solving. But there are a couple of conditions you must set: Make sure the bottom of the ramp is horizontal, and secured to the edge of the table top . Make sure the ramp is sufficiently high so that the ball can be released from a vertical height of 50cm Data and Observations: Record and neatly display whatever data you recorded to help you solve this problem. Include a labeled graph of the ball's flight showing horizontal (dx) and vertical (dy) displacements. Questions: 4. Why do projectiles follow a parabolic path? 5. What was the launch speed of your projectile? Include all relevant calculations. 6. What was the final velocity of your projectile? Include all relevant calculations Conclusions: State the answer to your purpose. Also, include one artifact (problem in the experimental design, NOT human error) that may have affected your results and led to experimental error, with explanation
