Aman pushes a box of 40kg up incline of 15°, if the man applies a horizontal force of 200n and the box moves up the plane a distance of 20m at a constant velocity and the coefficient of friction is 0.1, find work done against friction

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.
