Which of the following statements can be explained by Newton's first law? (A) When your car suddenly comes to a halt, you lunge forward. (B) When your car rapidly accelerates, you are pressed backward against the seat. O Neither A nor B O Both A and B O A but not B O B but not AIn Case A an object is moving straight downward with a constant speed 019.50 rm's. while in Case 8 an object is moving straight downward with a constant acceleration of magnitude 9.50 M2. Which oneof the following is true? 0 A nonzero net external force acts on the object in both cases 0 A nonzero net external force acts on the object in neither case. 0 A nonzero net external force acts on the object in Case Aonly. O A nonzero not external force acts on the object In Case B only. Two objects with masses m, and my are separated by a distance 2d. Mass my is greater than mass my. A third object has a mass m3. All three objects are located on the same straight line. The net gravitational force acting on the third object is zero. Which one of the drawings correctly represents the locations of the objects?
