Keshaun and myra went to the amusement park last summer. They noticed that the roller coaster was slower on the way up but went fast as they were on there way down. Keashaun's favorite part was the first drop, but myra liked when they were going a little slower.

Which statement correctly describes the relationship between frequency and wavelength?

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz. what wavelength is produced?

Aperson stands on a platform, initially at rest, that can rotate freely without friction. the moment of inertia of the person plus the platform is ip. the person holds a spinning bicycle wheel with its axis horizontal. the wheel has moment of inertia iw and angular velocity ωw. take the ωw direction counterclockwise when viewed from above. part a what will be the angular velocity ωp of the platform if the person moves the axis of the wheel so that it points vertically upward?
