An object is observed in a certain reference frame to move from the position [3.0 m, 2.5 m, -1.0 m] to the position [-1.0 m, 4.5 m, -2.0 m] during a time interval of 0.50 s. (A) What is the object’s displacement during this interval? (Write your answer as a column vector.) (B) What are the components of the object’s velocity during this interval? (Assume that the time interval is sufficiently short that the velocity is essentially constant.) = - = - = m 1.0 - m 2.0 m 0 . 4 - m 1.0 - m 2.5 m 0 . 3 m 2.0 - m 4.5 m 0 . 1 - i f r r r = = = m/s 2.0 - m/s 4.0 m/s 8.0 - s 5 . 0 1
