This question is based on the lab activity "Kinematics of Flying Q-tips". In this lab, students initially blow a Q-tip (ie. a cotton swab) through a straw horizontally. By measuring the original launch height and launch distance, it is possible to calculate the initial velocity of the Q-tip when it leaves the straw. By measuring the distance the Q-tip travels through the straw, it is possible to determine the average force the Q-tip experiences inside the straw. Finally, by moving the Q-tip to a new location in the straw and blowing the Q-tip again, it is possible to determine a new launch velocity and predict a new horizontal distance experienced by the straw. Use the data provided below and complete the steps indicated. You will enter your FINAL answer into Canvas, then upload a picture of your work. For your calculations, assume that g = -d 10 m/s². 1. Suppose the student holds the straw 1.7 m above the ground and blows the Q-tip horizontally so that it lands 3.8 m away. Use kinematics equations to determine the velocity of the Q-tip when it left the straw. Record your answer in units of m/s on your paper. 2. If the Q-tip traveled a distance of 10 cm inside the straw, use the Work-Kinetic Energy theorem to determine the average force experienced by the Q-tip inside the straw. Assume the Q-tip has a mass of 0.012 kg. (Be careful with your units on this question). Record your answer on your paper in units of N. 3. The Q-tip is put back in the straw so that it travels a distance of 14 cm inside the straw. Calculate the new launch velocity of the Q-tip. Record your answer in units of m/s on your paper. 4. Assuming the Q-tip was launched from the same height as step 1, calculate the new horizontal distance that the Q-tip should travel before hitting the ground. Record your answer to two decimal places in units of m. Enter this answer as your final answer in Canvas. Remember to upload a picture of your work on the next question.
