Auniform metal rod, with a mass of 2.6 kg and a length of 1.5 m, is attached to a wall by a hinge at its base. a horizontal wire bolted to the wall 0.70 m above the base of the rod holds the rod at an angle of 28 ∘ above the horizontal. the wire is attached to the top of the rod. find the tension in the wire. find the horizontal component of the force exerted on the rod by the hinge. find the vertical component of the force exerted on the rod by the hinge.

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.
