2 Take the acceleration due to gravity as g = 9.8 m s Question 4 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? O Object A will travel twice as far as object B. O Object A will be moving eight times faster than object B. Object A will travel four times as far as object B. O Object A will be moving four times faster than object B. O Object A will travel eight times further than object B. Question 5 Which one of the following situations is not possible? O A body travels with an eastward velocity and an eastward acceleration. O A body has zero velocity and non-zero acceleration. O A body travels with a time-varying velocity and a constant acceleration A body travels with an eastward velocity and a westward acceleration. O A body travels with a constant velocity and a time-varying acceleration. Question 6 A projectile is fired with a horizontal velocity from the top of an h = 81.1 m high cliff. The projectile strikes the ground x = 1,328 m from the base of the cliff as seen in the image. The drawing is not to scale. y (m) x (m) Determine the initial speed of the projectile. Give your answer to 0 decimal places
