Which three of the following descriptions are true of wave motion? Check all that apply.
O Waves involve the movement of matter from one location to another.
As waves pass through a medium, particles of the medium undergo a back-and-forth
vibration about a fixed position.
Waves involve the transport of energy from one location to another.
Nonsense! None of these describe wave motion.
Waves involve periodic and repeated disturbances of the medium.

The force will determine the acceleration.

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
