1. You are driving down the freeway at a constant 60 mph (26.8 m/s)·There is a...
An airplane is flying at 250 m/s due north, relative to air. There is a strong wind of 65 m/s blowing in a due east direction. Sketch a Vector Diagram showing the velocity of the airplane relative to the air, the velocity of the wind, and the final velocity of the plane relative to the ground. Use it to help you determine the magnitude and direction of the velocity of the plane relative to the ground.
2D Kinematics Question: A plane is flying 162 m/s west relative to the air. The wind is blowing 23 m/s north relative to the ground. Determine the plane's velocity relative to the ground. Velocity relative to the ground (magnitude)= Velocity relative to the ground direction = degrees W of N
plz dont skip steps (1 pt) A plane is heading due west: its nose points towards the west direction, but its trajectory on the ground deviates from the west direction due to a sideways component of the wind. The plane is also climbing at the rate of 120 km/h (height increase per unit time). If the plane's airspeed is 550 km/h and there is a wind blowing 90 km/h to the northwest, what is the ground speed of the plane?...
1. If an airplane, with airspeed = 100 m/s, is traveling directly against a wind of 20 m/s (relative to the Earth), how long does it take to travel from city A to city B if the cities are 40000 m apart? 2. If the wind in question #1 was perpendicular to the velocity of the plane relative to the air, what would the speed of the plane be relative to the Earth?
You are driving at a velocity of 95 MPH (42.5 m/s) when you hear a police siren behind you. From your previous run-ins with the law, you know that at a particular point in the sound, the police sirens on the police cars in your town emit a frequency of 751.255 Hz. You hear the sound at a frequency of 752.551 Hz. How fast the the police car going (in m/s)? (Assume that the speed of sound is 343 m/s.)
A small airplane is flying at a constant altitude with a ground speed of 75 m/s. The pilot needs to reach a point exactly 100 km north of her current location. However, there is a cross wind blowing at 20 m/s in a direction 30 degrees north of east. a. In what direction should the pilot point the plane so that she arrives at her destination as directly as possible. b. How long does it take to complete this part...
You are driving down the road at 15.6 m/s (35 mph) when an ambulance passes you with its siren blaring. The ambulance siren produces a frequency of 700 Hz. As the ambulance approaches you from behind, you hear a frequency of 730 Hz . The speed of sound in air is 344 m/s. What is the speed of the ambulance? The positive direction points from your car (listener) toward the ambulance (source). Express your answer in meters per second.
A model airplane competition has the following rules: Each plane must fly to a point 1 km from the start and then back again. The point km winner is the plane with the shortest round-trip time. The contestants are free to launch their planes in any direction, so long as the plane travels exactly 1 km out and then returns. On the day of the race, a steady wind blows from the north at 8.5 m/s. Your plane can maintain...
The car in front of you is driving through downtown Huntington at 35 mph (15.65 m/s). If the tires have a 17-inch diameter (the radius is 0.216 m), what is the angular velocity of the wheel in rad/s? What is the angular velocity in rpm?
You are driving down the highway at 14.9 m/s when you approach an automobile accident on the side of the road. To keep traffic away from it, a stationary police car has its siren going; to the police, the siren has a frequency of 1100 Hz. If the speed of sound in air is 332 m/s, what frequency (in Hz) will be heard by you in your car? If the relative motion in the previous question was reversed (i.e. if...
