Answer to Question #182395 in Classical Mechanics for Karungari Migwi

Question

Two blocks (m=16 kg and M=89.5kg) are in contact, but not attached to each other. The coefficient of static friction between the blocks is 0.383, but the surface between the larger block is frictionless. What is the minimum magnitude of the horizontal force F required to keep the smaller block from slipping down the larger block?

Answer 1

Answer

Minimum force required is

$F=\mu mg\\F=0.383(16) (9.81) \\F=60.12N$
