Create a plot based on the above formula of Time (t) [s] vs Displacement (Amplitute)(x)[in]. Time (t) to start from 0 to 30 secs, by 1 sec interval. Using the solver: a.) Identify the first three (3) times in seconds that the displacement is at 0[in] (use SOLVER) Identify in seconds the first \"MAX\" after 2.5 sec and b.) the first \"MIN\" displacement after the 2.5 sec in[in] (USE SOLVER) Time [s] Displacement Displacement [in] [in] 0 10 1 7.48 2 2.26 3 -2.31 4 -4.28 5 -3.58 6 -1.42 7 0.70 8 1.79 9 1.67 10 0.81 11 -0.15 12 -0.73 13 -0.77 14 -0.43 15 0.00 16 0.29 17 0.34 18 0.22 19 0.03 20 -0.11 21 -0.15 22 -0.11 23 -0.03 24 0.04 25 0.07 26 0.05 27 0.02 28 -0.01 29 -0.03 30 -0.02 Guess (s) Time (s) Disp (in) a1 2.5 a2 6.5 a3 10.8 b1 9.3 b2 4.1 MAX MIN

Examine the following graphs very carefully as each graph is scaled differently. Each question is worth 1 point unless otherwise indicated. This assignment is out of a total of 24 points. Part A: DISPLACEMENT TIME GRAPHS Neatly print the letter corresponding to what you think is the best answer in the box to the left of the question. You do not need to show any work. Questions #1-4 1. Calculate the velocity in the time interval of 0 to 5 seconds. a) 5 m/s b) -5 m/s c) 7.5 m/s d) -7.5 m/s 2. Calculate the displacement from time 0 seconds to time 7 seconds. a) 10 m b) -10 m c) 40 m d) 0 m 3. Calculate the distance traveled from 0 to 7 seconds. a) 10 m b) -10 m c) 40 m d) 0 m 4. During which time interval does the velocity have the greatest magnitude? a) 0 – 5 seconds b) 5 – 7 seconds c) Both have equal magnitude
