An Atwood machine is constructed using a
hoop with spokes of negligible mass. The
2.1 kg mass of the pulley is concentrated on
its rim, which is a distance 22.1 cm from the
axle. The mass on the right is 1.56 kg and on
the left is 1.93 kg. What is the magnitude of the linear acceler-
ation of the hangingmasses? The acceleration
of gravity is 9.8 m/s2 .
Answer in units of m/s2

Astone is thrown into a pond. what happens to the amplitude of the resulting waves as they get farther from the point where the stone hit the water? explain.

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.
