Walter arfeuille of belgium lifted a 281.5 kg load off the ground using his teeth. suppose arfeuille can hold just three times that mass on a 30.0° slope using the same force. what is the coefficient of static friction between the load and the slope?

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.
