Can I read Work Against Gravity and Friction on EtoBox?

Work Against Gravity and Friction by nicosanquilero2 is a document available to read on EtoBox.

What is Work Against Gravity and Friction about?

The document contains 3 physics problems about calculating work done by various forces: 1) Calculating the work done by friction to slide a 300g object 80cm along a table with a coefficient of friction of 0.2. The work equals -0.47J. 2) Calculating work done against gravity to lift a 3kg object 40cm vertically. The work equals 12J. 3) Calculating the work done by the supporting force and gravitational force to lower an object through a vertical distance h. Both forces do work of mgh.
