Transcribed Image Text:

A 0.27 kg slab of fine mahogany wood block is held against a wall at rest. The coefficient of static friction between the wall and the mahogany slab is 0.43. A spring of spring constant 115 N/m is attached to the mahogany slab and the spring is compressed with a force directed perpendicular to the wall to keep the slab at rest. Figure mg (a) Determine the minimum compression of the spring needed, in cm, in order to keep the slab at rest. spring displacement increases by a factor of 3 spring displacement decreases by a factor of 3 spring displacement increases by a factor of 9 spring displacement decreases by a factor of 9 spring displacement is unchanged cm (b) The mahogany slab is to have its mass tripled. How much will the answer to part (a) change due to the change in mass? A 0.27 kg slab of fine mahogany wood block is held against a wall at rest.
