Homework Statement
Two blocks, A and B, are connected by a compressed string. The mass of bock A is twice that of block B. Immediately after release, compare the net force on block A to the net force on block B. The table is frictionless and the mass of the spring is zero.
1)There is no net force on block A or block B.
2)Fnet of A is equal in magnitude and direction to Fnet B and not zero.
3) Fnet B, will be in the opposite direction and half as large as Fnet A.
4)Fnet A, and Fnet A are both directed toward the left with Fnet A larger than Fnet A, but not twice as large. Block A is pulling block B.
5) Fnet A, will be in the opposite direction and half as large as Fnet B.
6) Fnet A is equal in magnitude and opposite in direction to Fnet B, and not zero.
Homework Equations
I don't think you need any equations.
The Attempt at a Solution
I think it is 5 because A is twice as massive as B so it would take more force to move it the the same and they will be going in opposite directions. Do you agree?
