1. Consider the position vs time graph for objects A and B below. a. Draw qualitative motion maps for objects A and B. Include v and a vectors. b. Describe how the motion of object A is different fr ... om that of object B. c. Qualitatively compare the following quantities for objects A and B. If A has the greater value write "A" in the blank. If B has the greater value write "B". If A=B write "=". Displacement from t = 0 s to t = 5s Displacement from t = 0 s to t = 2.5s Displacement from t = 2.5 s to t = 5s Average velocity from t = 0 s to t = 5s Average velocity from t = 0 s to t = 2.5s Instantaneous velocity at t = 5s A position (m) 5 time (s) B 2.5 vel: acc: 0m + vel: acc: 0m + A: B: ©Modeling Instruction 2013 2 U3 Uniform Acceleration - test v3.1 2. Consider the velocity vs time graph for objects A and B below. a. Draw qualitative motion maps for objects A and B. Include v and a vectors. b. Qualitatively compare the following quantities for objects A and B. If A has the greater value write "A" in the blank. If B has the greater value write "B". If A=B write "=". Instantaneous velocity at t = 0 s Instantaneous velocity at t = 2.5s Instantaneous velocity at t = 5s Average velocity from t = 0s to t = 2.5s Average velocity from t = 0s to t = 5s Displacement from t = 0 to t = 2.5s Displacement from t = 0 to t = 5s Acceleration at t = 5s.

Your teacher's car can go from rest to 25 m/s (≈60mph) in 10 seconds. The car's velocity changes at a uniform rate. a. Draw a qualitative motion map to represent the motion of the car during the 10 s. Include v and a vectors. b. Construct a quantitative velocity vs time graph to represent the motion of the car. c. Determine the acceleration of the car. Show work; use units. d. How far does the car travel in these 10 seconds? Explain or show how you got your answer. [Show More]
