Which mo%on has constant nega%ve velocity? x A B C t D E) None of these, or MORE THAN ONE of them! Room Frequency BA Clicker Ques3on Which mo%on has constant nega%ve velocity? E - None A x (m) B C D t (s) Only D has a constant nega%ve slope, Jan. 23, 2013 therefore constant nega%ve velocity. 8 Room Frequency BA Clicker Ques3on The velocity of object D is approximately? E - None A x (m) A)  - 1.33 m/s B)  - 0.75 m/s C)  0.0 m/s D)  +0.75 m/s E)  +1.33 m/s B C D t (s) B: The slope of line D is Δx/Δt=(-3.0 m)/(+4s) = - 0.75 m/s.
