H. DE-2 Ray is driving his car at a speed of 25 M/S when he sees a truck in front of him coming toward him with a speed of 35m/s. Ray honks his horn, which has a fregquency of 1,750 Hz, at the truck. a) Make a sketch of the situation showning Ray's car, the truck, and their velocities. b) Find the frequency heard by the truck. c) The sound from Ray's horn reflects off of the front vertical surface of the trúck and Ray hears the echo. Find the frequency heard by Ray by first sketching the situation and then doing the calculation. Be carefui; now the truck is the source (of the reflected wave) and Ray is the receiver. 工 工
