Question 1 PRACTICE ASSIGNMENT Indicate if each of the following statements is either true (7) or false (F). 目 回 GIVEN: Mar. 7th a) Average acceleration is defined to be the change in velocity over the change in time. b) A car moving at a speed of 95 km/hr on cruise control is an example of uniform motion. c) In the case where a large number of tilted (angled) vectors are to be combined, the scalene triangle method (cosine law/sine law) is both faster and more accurate than is the vector decomposition method. d) An object is thrown vertically up. After 3 s, it has lost 29.4 m/s of its original launching speed. e) For some very special cases, displacement can be larger than distance. f) The following relative motion vector equation is valid KR =>>KF +RF g) When an east-pointing vector is subtracted from a north-pointing vector, the resultant vector must point somewhere in the north-west quadrant. h) When a runner finishes her run around a circular track (by going back to her starting point), only her distance is zero.
