Question 1 Not yet answered Marked out of 2.00 \\V Flag question Consider the following Position-Time graph showing the Altitude of a Rocket as a function of time. t : 0 is the moment the rocket "launches" from the ground. 0 c c c Altitu d (m) 4008 2000 Time (3 Explain how you can tell that the shuttle is SPEEDING UP. In your explanation, refer to the "slope". Question 2 Not yet answered Marked out of 2.00 \\V Flag question The rocket (see question 1) will continue to accelerate until it reaches its maximum speed of 7000 m/s. The position-time graph of the rocket will beEwhen the rocket is moving at maximum speed. The velocity-time graph of the rocket will be S when the rocket is moving at maximum speed.

Attach the graph to this question's dropbox. You can graph on paper or using technology. (1 mark) b) Explain how you could use positiontime data to determine the ACCELERATION of the object. Do not complete the calculation, just explain the steps you would take. (3 marks) Question 6 Not yet answered Marked out of 9.00 \\V Flag question You are riding in an elevator. Starting from rest, the elevator undergoes the following motions: 0 It accelerates from rest (v = 0.0 m/s) upwards for 5.0 s at +2.0 m/sz. 0 It then coasts for 20.0 s at 10.0 m/s (a = 0.0 m/sz). 0 After 20 seconds of uniform motion, it accelerates downward for 2.5 s at 4.00 m/sz. Complete the following graphs based on the motion described above. 3 marks per graph. a) PositionTime Graph b) VelocityTime Graph 0) AccelerationTime Graph \"5'i" 7 Basam is standing on the edge of a cliff and tosses her physics book upward with a speed of 22.0 m/s.

You may assume that the acceleration of the 4.00 textbook is 9.8'l m/SZ. '7 \"39 Use the graph to determine (2 marks each): question a) the height of the cliff. b) the speed of the book when it impacts the ground. DO NOT use kinematics formulas to solve this problem. This task is assessing your understanding of GRAPHING to represent accelerated motion. Paragraph v (.1 E 5/ 215
