Jimothy is riding his bike to his friend's house. He decides to see how fast he can go, and starts pedaling as hard as he can. He began with an initial velocity of 2.5 m/s. He pedals with an acceleration of 1.5 m/s^2 for a time of 6 seconds. Calculate his final velocity.

The correct option is this: the sound waves from the two trombones have slightly different frequencies.from the question given above, we are told that the loudness of the sounds were increasing and decreasing, this is because the frequencies of the two sounds are different. the means that the number of waves that pass a fixed point in a given amount of time differ for both sounds.
