Four identical blocks are moving on a surface for which the coefficient of kinetic friction between each block and the surface is µ_k.The velocity of each block is indicated by the vector on the block.For which block is the force of friction between the surface and the block greatest? A)1 B)2 C)3 D)4 E)The force of friction is the same for all blocks.

Question

Quizplus · Accepted Answer

Since all the blocks are identical and have the same coefficient of friction with the surface, the force of friction will be the same for all of them. Therefore, the correct choice is E, the force of friction is the same for all blocks.
