A car passes and moves away from you at 110 km/hr as you stand on the side of the highway in 28 C weather. o The driver gives a long beep on the horn. If the horn makes a 450 Hz sound, what frequency do you hear?

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
