To move a resting box of 100 newton on the ground with kinetic friction coeficient of 0,250 is applied a force of 60 n horizontally and displacing it 10 m. how much work does applied force do? how much work is done against friction force? what is kinetic energy of the box?
the planet mars is visible without a telescope on many clear nights. the planets jupiter, mercury, venus and saturn are also viewable without the aid of magnification.
