A train emits a normal frequency ( f) of 300 Hz. What shifted frequency ( fs) will you hear if the train moves at 35.0 m/s AWAY from you? The following information is given to you: Speed of sound = 343 m/s. fs = f x [v / (v - vs) ］ fs = f x [v / (v + vs) ］

The answer would be a) -80of

Answer(b) both involve the use of levers;

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.
