Experiment two_ Projectile motion

In an inertial frame of reference S, an observer finds two events occurring at the same time at coordinates x, = 0 and x, = d. A different inertial frame S' moves with velocity v with respect to S along the positive x-axis. An observer in S'also notices these two

General instructions: In case of Multiple choice, Write the letter of your answer. In case of True or False, write T if the statement is true and write F if the statement is False. Write all your answer in the space provided after the number. In case of Problem Solving, write all your computations and always encircle your final answer. Kinematics 2: Motion in 2-Dimenstions and 3-Dimensions 1. A passenger in a bus moving at constant velocity tosses a coin. An observer standing at the side of the road sees the coin being tossed. True or False? The passenger sees the coin follows a parabolic path. 2, A passenger in a bus moving at constant velocity tosses a coin. An observer standing at the side of the road sees the coin being tossed. True or False? The outside observer sees the coin foilows a parabolic path. 3. A passenger in a bus moving at constant velocity tosses a coin. An observer standing at the side of the road sees the coin being tossed. True or False? Neither the passenger, nor…

Part A Drop Tower NASA operates a 2.2-second drop tower at the Glenn Research Center in Cleveland, Ohio. At this facility, experimental packages are dropped from the top of the tower, on the 8th floor of the building. During their 2.2 seconds of free fall, experiments experience a microgravity environment similar to that of a spacecraft in orbit. What is the drop distance of a 2.2-s tower? Express your answer using two significant figures. ΑΣΦ ? Submit Request Answer • Part B How fast are the experiments traveling when they hit the air bags at the bottom of the tower? Express your answer using two significant figures. ? m/s Submit Request Answer • Part C If the experimental package comes to rest over a distance of 0.74 m upon hitting the air bags, what is the average stopping acceleration?
