2.2 speed and velocity\n11. is it possible to determine a cars instantaneous velocity from just the speedometer reading?\na. no, it reflects speed but not the direction.\nb. no, it reflects the average speed of the car.\nc. yes, it sometimes reflects instantaneous velocity of the car.\nd. yes, it always reflects the instantaneous velocity of the car.

2.2 speed and velocity\n11. is it possible to determine a cars instantaneous velocity from just the speedometer reading?\na. no, it reflects speed but not the direction.\nb. no, it reflects the average speed of the car.\nc. yes, it sometimes reflects instantaneous velocity of the car.\nd. yes, it always reflects the instantaneous velocity of the car.

Answer

Brief Explanations:

Velocity is a vector quantity that includes both speed and direction. A speedometer only shows the magnitude of the rate of motion (speed) and not the direction of the car's motion. So, it cannot determine the instantaneous velocity.

Answer:

a. No, it reflects speed but not the direction.
