Projectile motion - Data Analysis Data Analysis The same projectile experiment was conducted as you did in class. A racquet ball rolls down a track, leaves the track at an initial height of 0.96 1m above floor, with an exit speed V. = 1.40m/s at an angle d - 7.46". The landing spot was repeatedly measured for ten times, and the racquet ball's horizontal range data is provided below. Data run 5 6 10 Landing spot 0 585 0.590 0.595 0 590 0.585 0.580 0 580 0.585 0.580 0.575 (m] Question 1: (3 points] Please determine the & and y components of the racquet ball's initial velocity below (use downward direction as the positive direction.) Question 2: (3 points) Please determine the flight time of the racquet ball below. Question 3: (3 points] Please use the velocity components and the flight time to calculate the horizontal range of the racquet ball. Question 4: (3 points] Please process the measured horizontal range data in Excel to determine the mean, the standard deviation and the standard error of the range. Mean Standard Deviation Standard Error Horizontal Range (m): Question 5: (4 points) Please calculate the 95% confidence range of the horizontal range, and report your result in the format of mean + 95% range (refer to the Uncertainty-docx document for the correct format-) Question 6: (4 points) In our study of projectile motion, we often say that air drag can be neglected without loss of accuracy for low speed objects. is this assertion true? Let's compare the calculated range in Question 3 and the mean of the measured range in Question S. If the calculated value agrees/disagrees with the measured value, then the assertion is true/false for this case. Does the calculated value agree with the measured value within its 95% confidence range
