QUESTION 4 It is year 2321, and humans colonized Mars. You are in an elevator on a Martian skyscaper and you are standing on a bathroom scale of mass 1.1 kg. Your mass is 74.3 kg. The mass of the elevator car is given as 1,175 kg. While the elevator is moving you notice that the bathroom scale shows your weight as 325.2 Newtons. What should be accelaration of the elevator at the moment you read your weight? Enter your answer by taking the upward direction as the positive direction in units of m/s. (accelaration due to gravity magnitude on Mars surface is 3.75 m/s2)
X 0 C. Kinematics Graphs: Comparison Practice 5 e. A B 6 1. Two identical objects, A and B, move along straight, parallel, horizontal tracks. The graph above represents the position as a function of time for the two objects. t a. At approximately which time or times, if any, are the objects moving at the same speed? If the objects are never moving with the same speed during the interval shown, indicate this explicitly. Briefly explain your answer. b. (b) Describe what is happening to the positions of objects A and B between 0 seconds and 1 seconds. Describe what is happening to the positions of objects A and B between 4 seconds and 5 seconds. d. Which object, if either, has an acceleration with a greater magnitude during the time interval shown in the graph? If the accelerations have the same magnitude for both objects, indicate this explicitly. In a clear, coherent, paragraph-length response, explain your response to part (d). Be sure to reference and compare the graphed information…

6. A train is moving with a constant speed. The train moves 60 meters for every 1.5 seconds that elapses. a. Assume that we get 40 by dividing 60 by 1.5. What is the name that is commonly given to a quantity represented by this number 40? b. To denote the quantity completely, what additional information must be given besides the number 40? c. How would you interpret the number 40 in this instance? Your answer should mention distance and time. d. Use your interpretation (not algebra) to find the distance the train moves in 2.5 seconds.

13. On a distant planet, an astronaut drops a steel ball from a height of 150 meters. He observes that it takes 10 seconds for the ball to reach the surface of the planet. The distance that the ball falls from the starting point is recorded with the instruments that he carries in his spaceship, with this, he generates the table shown below. Using the data provided, determine the gravitational acceleration corresponding to the planet the astronaut is on. Write the answer using two significant figures.
