Two blocks are connected by a massless rope that passes over a 2 kg pulley with a radius of 5 cm. The rope moves over the pulley without slipping. The mass of block A is 2 kg and the mass of block B is 3 kg. Block A is also connected to a horizontally-mounted spring with a spring constant of 150 J/m2. What is the period (in s) of simple harmonic oscillations of this system?

Which of the following is an example of motion in two dimensions?

Identify the theory that can be used to explain each phenomenon. answers diffraction: wave theory interference: wave theory reflection: both particle and wave theories refraction: both particle and wave theories

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
