Reference no: EM13524692

The sound of a truck horn, observed when the truck is stationary, is 440 Hz. A drunk is sitting in the middle of the road at night. He sees the truck's headlights, and hears a 480 Hz horn. How rapidly is the truck approaching him, in m/s2? In mph? (As before, assume the speed of sound in air is 343 m/s.)
