2. A 2.0 MHz sound wave travels through a pregnant woman's abdomen and is reflected from the fetal heart wall of her unborn baby. The heart wall is moving toward the sound receiver as the heart beats. The reflected sound is then mixed with the transmitted sound, and 85 beats per second are detected. The speed of sound in human body is 1500 m/s. Calculate the speed of the fetal heart wall at the instant this measurement is made.
