Does the speedometer of a car measure speed or velocity? Explain.

Expert Solution & Answer

To determine

The speedometer of the car measure the speed or velocity.

Answer to Problem 2.1DQ

Speedometer does not measure the direction of the car this means that speedometer will not measure the velocity of the car. Therefore, the speedometer is measure speed of the car.

Explanation of Solution

The speed is defined as the ratio of the distance travel by the particle to the time taken by the particle. Speed is a scalar quantity.

The velocity is defined as the ratio of the displacement of the particle to the time taken by the particle. The velocity is a vector quantity and the direction of velocity is same as the direction of displacement.

Conclusion:

Speedometer does not measure the direction of the car this means that speedometer will not measure the velocity of the car. Therefore, the speedometer is measure speed of the car.

13.87 ... Interplanetary Navigation. The most efficient way to send a spacecraft from the earth to another planet is by using a Hohmann transfer orbit (Fig. P13.87). If the orbits of the departure and destination planets are circular, the Hohmann transfer orbit is an elliptical orbit whose perihelion and aphelion are tangent to the orbits of the two planets. The rockets are fired briefly at the depar- ture planet to put the spacecraft into the transfer orbit; the spacecraft then coasts until it reaches the destination planet. The rockets are then fired again to put the spacecraft into the same orbit about the sun as the destination planet. (a) For a flight from earth to Mars, in what direction must the rockets be fired at the earth and at Mars: in the direction of motion, or opposite the direction of motion? What about for a flight from Mars to the earth? (b) How long does a one- way trip from the the earth to Mars take, between the firings of the rockets? (c) To reach Mars from the…
