A block weighing 100 N is placed on an inclined plane of slope angle 30 degrees and is connected to a second hanging block of weight “W”, by a cord passing over a small frictionless pulley. The coefficient of sliding friction is 0.3. Find the weight “W” for which the 100N block moves up the inclined plane at a constant velocity.

Complete solution, please. Thanks!

Coefficient of friction is 0.30. A homogeneous block weighs W rests upon the incline as indicated. Determine the highest height at which a force P parallel to the incline could be applied so that the block will slide up the incline without tipping over. Show FBD drawing of block and forces

Ex-6. A steel tape with a cross-sectional area of 0.039 cm²and weighing 0.909 kg has a length of 30.009 m. when supported throughout 20°C and subject to a tension of 5.5 kg. This tape is used to measure a distance along a uniform 4% grade and is supported throughout during the measurement. The tension applied is 12 kg. The temperature of the tape is 2°C. The measured slope distance is recorded 381.615 m. What is the corrected horizontal distance? AMa
