3) A sports car is speeding toward you down the road. The car is traveling at 25.2 meters per second and the exhaust produces sound waves with a frequency of 845 Hz. Find the observed frequency as the car is driving towards you and when the car is driving away from you. How do they compare? Would you notice the difference in the sounds? Use 343 m/s for the speed of sound.

A car with a mass of 980 kg is initially traveling east toward
an intersection with a speed of vc = 20.9 m/s
and a 1500 kg pickup is traveling north toward the same
intersection. The car and truck collide at the intersection and
stick together. After the collision, the wreckage (car and truck)
moves off in a direction of 44.0° above the x-axis.
Determine the initial speed of the truck and the final speed of
the wreckage in meters...

Part A. The sports car, having a mass of 1700 kg, is traveling
horizontally along a 20° banked track which is circular and has a
radius of curvature of ρ = 100 m. If the coefficient of
static friction between the tires and the road is
μs = 0.2 . Determine the maximum constant speed
at which the car can travel without sliding up the slope. Neglect
the size of the car.
Part B. Using Data in Part A, determine...
