Question
The two blocks shown here are in contact on a frictionless surface. Suppose that someone comes along and begins pushing on the left side of block 1, causing both blocks to begin to slide to the right. Assuming you will study the system composed of ONLY block 2 treated as a single point particle, determine which of the following interactions are internal to the system and which are external.
internalexternalnot relevant to this systemnot a valid interaction The contact interaction between block 1 and block 2.
internalexternalnot relevant to this systemnot a valid interaction The contact interaction between the person pushing the blocks and block 1.
internalexternalnot relevant to this systemnot a valid interaction The gravitational interaction between the earth and block 2.
internalexternalnot relevant to this systemnot a valid interaction The contact interaction between the person pushing the blocks and block 2.
internalexternalnot relevant to this systemnot a valid interaction The contact interaction between the frictionless surface and block 1.
The answers can be: external, internal, not a valid interaction, or not relevant to the system
