What else can I help you with?
The speedometer of a car moving to the east reads 100km per hr and it passes another car that moves to the west at 100km per hr so do both cars have the same velocity please explain?
Velocity is direction and speed so the vehicle do not have the same velocity
What type of velocity does the speedometer on a car measure?
The speedometer on a car measures the vehicle's instantaneous speed or linear velocity, which is the rate of change of its position over time. This velocity indicates how fast the car is moving at any given moment.
The speedometer of a car moving east reads 55mph it passes another car going west at 55mph the cars have the same?
Speed - but NOT velocity.
Does a speedmeter give instantaneous speed or velocity?
Velocity is a vector quantity, so a different direction makes a different velocity. Speed is a scalar quantity, where direction makes no difference. Since a speedometer reads the same regardless of direction of motion, it is providing speed, not velocity.
A 80 kg student traveling in a car with a constant velocity has a kinetic energy of 1.5 x104 J What is the speedometer reading of the car in?
Kinetic energy = 1/2 M V21/2 (80) V2 = 15,000V2 = 15,000/40 = 375V = sqrt(375) = 19.365 meters/secIf the student is enrolled at the Sorbonne or McGill, the speedometer reads 69.7 km/hr.If the student goes to MIT or Univ. of Rochester, the speedometer reads 43.3 mph .
Does both car have same velocity If a speedometer on a car travelling north reads 65 km per hr and it passes another car travelling south at 65 km per hr.?
No, the car donot have same velocity.
If the speed of your car reads 40 km - Hr can you say the car has a constant velocity?
Yes, if you are also going in the same direction the entire time.
What speed are you actually traveling at when your speedometer reads 55mph?
Unless you have a broken speedometer, you are traveling at 55 mph.
Does the speedometerof a car read average speed or instantaneous speed?
The speedometer in a car does not measure the car's velocity because velocity is an (A) vector quantity and has a direction associated with it (B) vector quantity and does not have a direction associated with it.
Will changing gear ratio change speedometer?
Yes. The speedometer reads off the transmission tail shaft, and the speedometer is geared (in a mechanical system) or programmed (in an electronic system) accordingly.
Which type of speed is on a speedometer?
It reads instantaneous speed, and tells you nothing about average speed.
2004 Honda Civic with Speedometer Problems?
I have a 2004 Honda Civic. The Speedometer rests at 35 MPH and when traveling at 55 MPH, it reads 85MPH.
