You have an unpowered cart, the Pasco Track, and the sonic detector. You must design a method to determine the speed of the cart after it has traveled a specified vertical distance down the track inclined at 5 or 15. YOU MAY NOT USE ANY OTHER INCLINE. When you have collected your data and developed a method, your instructor will provide you with your incline angle and vertical drop. You MUST fully explain how you arrived at your answer and the uncertainty including supporting data. Hint: In this, as in all other experiments, you should think abo
