What force must be applied to end of a rod along the x-axis of length 2.0 m in order to produce a torque on the rod about the origin of 8.0\(\hat{k}\) N • m? Assuming the lower end of the rod does not slip, what is the linear velocity of the upper end when it hits the floor?

We concentrate on mechanical waves, which are disturbances that move through a medium such as air or water. Like simple harmonic motion studied in the preceding chapter, the energy transferred through the medium is proportional to the amplitude squared. The concepts presented in this chapter will be the foundation for many interesting topics, from the transmission of information to the concepts of quantum mechanics.

(a) Show that the spring exerts an upward force of 2.00mg on the object at its lowest point. (b) If the spring has a force constant of 10.0 N/m, is hung horizontally, and the position of the free end of the spring is marked as y = 0.00 m, where is the new equilibrium position if a 0.25-kg-mass object is hung from …

(We’ll neglect the gravitational force of the sun.) Thus, if we calculate the change of momentum of the lander, we automatically have the change of momentum of the comet.

(a) If the damping is small (b < \(\sqrt{4mk}\)), the mass oscillates, slowly losing amplitude as the energy is dissipated by the non-conservative force(s).
