    Center of Mass Identical Size Object Connected by Spring

    Homework Statement Two identical 0.19 kg blocks (labeled 1 and 2) are initially at rest on a nearly frictionless surface, connected by an unstretched spring, as shown in the upper diagram, where x2 = 0.05 m. Then a constant force of 8 N to the right is applied to block 2, and at a later time...
  2. C

    Yes, that gives the correct answer.

    b. If the change in momentum vector points opposite the direction of motion, the object slows down. True. If the change in momentum vector points opposite the direction of motion, then the object is losing momentum, which means it is slowing down.
  3. C

    Yes, that gives the correct answer.

    How is my logic? a. If the net force points in the direction of motion, the object speeds up. True, if a force is applied in the direction of motion (F=ma) the mass stays the same, so the acceleration of the object must increase. b. If the momentum vector points opposite the direction of...
  4. C

    Yes, that gives the correct answer.

    I tried a,b,d - but it was also incorrect - I don't understand what I am missing. The object has constant momentum, which indicates there are no forces acting on it. Is it possible for the momentum vector to point opposite the direction of motion?
  5. C

    Yes, that gives the correct answer.

    Homework Statement Which of the following statements are true? (Select all that apply.) 1 a. If the net force points in the direction of motion, the object speeds up. If the change in b. momentum vector points opposite the direction of motion, the object slows down. c. The net force...
