An ambulance traveling eastbound at 162.0 km/h with sirens blaring at a frequency of 6.50 × 102 Hz passes cars traveling in both the eastbound and westbound directions at 47.0 km/h. (Assume the speed of sound is 343 m/s.) (a) What is the frequency observed by the eastbound drivers as the ambulance approaches from behind? 776.1 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. Hz (b) What is the frequency observed by the eastbound drivers after the ambulance passes them? 552.6 × Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. Hz (c) What is the frequency observed by the westbound drivers as the ambulance approaches them? 719.6 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. Hz (d) What is the frequency observed by the westbound drivers after the ambulance passes them? 596.7 × Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. Hz
