1. Homework Statement
Blocks of mass 5, 10, and 25 kg are lined up from left to right in that order on a frictionless surface so each block is touching the next one. A rightward-pointing force of magnitude 14 N is applied to the left-most block.
a) What is the magnitude of the force that the middle block exerts on the rightmost one?
Fright, middle = 8.749999995
b) What is the magnitude of the force that the leftmost block exerts on the middle one?
Fmiddle, left = ?
c) Suppose now that the left-right order of the blocks is reversed. Now find the magnitude of the force that the leftmost block exerts on the middle one?
F'middle, left = ?
i figured out the first part i just need help to do the last two
