6) In deep space, two rocks (rock A and rock B) are connected by a taut string and a compressed spring. Relative to you, the rocks are not moving. Then the string breaks, allowing the spring to expand and push the rocks in opposite directions. During this process, considering Newton’s Third Law, the spring:

a) Exerts more force on rock A than rock B
b) Exerts more force on rock B than rock A
c) Exerts the same amount of force on each rock
d) All of the above can be true depending on timing, although not simultaneously

anonymous · Answer

well can u draw it?

michele_laino · Answer

I think, that the answer is c), since I have applied the third law of Newton

anonymous · Answer

oh yes
i totally forgot that we have to apply Newtons law
sorry :)

michele_laino · Answer

here, the spring has to be view only as a connecting medium between the two rocks
