Amotorcycle is travelling at a constant velocity of 30ms. the motor is in high gear and emits a hum of 700hz. the speed of sound in air is 340ms, and there is no wind. a. what is the period of the sound waves emitted from the motorcycle? b. what is the distance travelled by the motorcycle during one period of the sound oscillation? c. what is the distance travelled by a sound wave in air during one period of oscillation? d. the humming of the motorcycle is a sound that is emitted in all directions and, once emitted, it travels in the reference frame of the still air at the speed of sound in air. consider the emitted sound that is moving directly out in front of the motorcycle

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.)
