SUMMARY

The discussion focuses on calculating the minimum horizontal force vector F required to prevent a 36 kg block from slipping down a 98 kg block, given a static friction coefficient of µs = 0.48 between the blocks and a frictionless surface beneath the larger block. The absence of a figure in the post hinders clarity, but the problem involves applying principles of static friction and Newton's laws of motion. Participants emphasize the need for a solution attempt to facilitate collaborative problem-solving.

PREREQUISITES

Homework Statement



The two blocks (m = 36 kg and M = 98 kg) in the figure below are not attached to each other. The coefficient of static friction between the blocks is µs = 0.48, but the surface beneath the larger block is frictionless. What is the minimum magnitude of the horizontal force vector F required to keep the smaller block from slipping down the larger block?

hmm, where's the figure? and also you are supposed to post an attempt to the solution..
