The S.I unit of velocity is m/s and since it's velocity it needs to be in a particular direction, therefore most appropriate answer is :
B. She is running west at 2.4 m/s
Answer: 0.50 m/s
Explanation: it’s on khan academy this was the correct answer
Answer:
The speed, magnitude of the velocity, magnitude of the angular velocity, magnitude of the centripetal acceleration, magnitude of the net force and direction of the angular velocity are constant.
Explanation:
In uniform circular motion we have a centripetal acceleration of constant magnitude but changing direction (since it points to the center of the circle from the object). The same goes for the net (centripetal) force since F=ma. This makes the magnitude of the velocity (speed) constant but its direction changes, although keeping spinning in the same direction, which makes its angular velocity constant in both magnitude and direction.
