How much work is done by a person who pushes a cant with a force of 200 newtons if
the cart moves 20 meters in the direction
of the fonce.

fgravity=10x10=100n case 1

fgravity=30x20=600n case 2

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

no. dot product   =0 when vecs at right angles
