Aparticular car engine produces a frequency of 250 hz. a student listening to the engine of the car hears a frequency of 880 hz. describe the motion of the car relative to the student.

Explanation:

given,

car engine produce frequency of = 250 Hz

student is listening frequency of = 880 Hz

speed of sound = 343 m/s

velocity of student = 0 m/s (at rest)

motion of car relative to student = ?

using formula

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s
