G What is the frequency of the train whistle as heard by a passenger on the train? n alert physics student stands beside the tracks as a train rolls slowly past. She notes that the train whistle has a frequency of 465 Hz as the train approaches her and a frequency of 445 Hz as the train moves away from her. The speed of sound is 343 m/s. While waiting for her own train to arrive, the student performs some ca

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.

Ithink it is a. but i'm not 100 percent sure.
