Question

1. measure and record the distance along the floor between the landing spot and the place where the ball left the track. if your measurements and calculations were accurate, this distance should be the same as the distance you calculated.
2. calculate the percent error between the predicted distance and the actual distance the ball traveled. (calculated distance - actual distance) x 100% / calculated distance
3. discuss some sources of error in the investigation that may have resulted in your ball not landing in the center of the target.

Explanation:

Step1: Recall percent - error formula

Percent error = $\frac{\vert\text{calculated distance}-\text{actual distance}\vert}{\text{actual distance}}\times100\%$

Step2: Measure actual distance

First, accurately measure the actual distance the ball travels along the floor from the point it left the track to the landing spot using a measuring tape or other appropriate measuring device.

Step3: Use predicted distance

Obtain the predicted distance (from a theoretical model, previous experiment, etc.).

Step4: Calculate percent - error

Substitute the values of calculated distance and actual distance into the percent - error formula and perform the arithmetic operations.

Answer:

Follow the above steps to calculate the percent error between the predicted and actual distance the ball traveled. For question 6, sources of error could include measurement errors (inaccurate use of measuring tools), air - resistance (if not accounted for in the prediction), and imperfections in the track surface that could affect the ball's motion.
