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.

Luis is installing some 12-gage wire. how much resistance will there be throughout a distance of 400 feet?

Acanon ball fired horizontally from a cliff has a velocity directed at 60 below horizontal from a cliff has a velocity directed at 60 below horizontal when it hits the ground 3.0 seconds later. a.) how high is the cliff? b.) how far from the base of the cliff does the canon ball land?
