Question

5. Starting from rest, a particle confined to move along a straight line is accelerated at a rate of 5.0 m/s Which one of the following statements accurately describes the motion of this particle? A) The particle travels 5.0 m during each second. B) The particle travels 5.0 m only during the first second. C) The speed of the particle increases by 5.0 m/s during each second. D) The acceleration of the particle increases by 5.0 m/s during each second. E) The final speed of the particle will be proportional to the distance that the particle covers. 6. Which one of the following situations is not possible? A) A body has zero velocity and non-zero acceleration B) A body travels with a northward velocity and a northward acceleration. C) A body travels with a northward velocity and a southward acceleration. D) A body travels with a constant velocity and a time-varying acceleration. E) A body travels with a constant acceleration and a time-varying velocity. 7. Two objects A and B accelerate from rest with the same constant acceleration. Object A accelerates for twice as much time as object B, however. Which one of the following statements is true concerning these objects at the end of their respective periods of acceleration? A) Object A will travel twice as far as object B. B) Object A will travel four times as far as object B C) Object A will travel eight times further than object B. D) Object A will be moving four times faster than object B. E) Object A will be moving eight times faster than object B.
