Transcribed Image Text:The 50-kg block in the figure is initially at rest on a horizontal plane. Determine the friction force between the block and
the surface after P was gradually increased from 0 to 245.25 N. In which phase will the block be classified (Phase 1- no
motion, Phase 2 - impending motion, or Phase 3 - in motion)?
