A The direclion of the rosultant is always different from the directions of the two original vectors. B The direction of the resultant is always the same as the direction of one of the original vectors. C The magnitude of the resultant is always different from the magnitudes of the two original veclors. D The magnitude of the resultant may be zero. 5 A car travels east at a velocity of25 m / s along a straight horizontal track. At time f = 5 s, its velocity starts to change and its acceleration is - 2.0 m / s2. How is the car moving at time I = l5s? A travelling east with decreasing speed B travelling east with increasing speed C travelling west with constant speed D travelling west with increasing speed Object X of mass m is released from a height h- Another object Y of mass 3m is released from a height 3h simultaneously lf both objects fall freely, taking air resastanc€ as negligible, which of the following statements is true? 6 A B c D The acceleration of both obiects increases. The distance between object X and Y decreases and Y overtakes X. The distance between ob,ect X and Y remains constant before object X hits the
