PLEASE HELP ME IM DESPERATE! You are pushing a 15 kg box across the floor. You are applying 30 N of force straight forwards. The coefficient of friction between the box and the floor is 0.35. List each force acting on the box and determine its magnitude.

Anonzero net force acts on a particle and does work. which one of the following statements is true? the kinetic energy of the particle changes, but the speed of the particle does not change. the kinetic energy of the particle does not change, but the speed of the particle does change. the kinetic energy of the particle changes, but the velocity of the particle does not change. the kinetic energy and the speed of the particle change, but the velocity of the particle does not change. the kinetic energy, speed, and velocity of the particle change.
