Answer:
Explanation:
Centripetal acceleration is given by:
Thus, centripetal acceleration is inversely proportional to the radius. Thus, when radius will double, the centripetal acceleration will be halved.
Answer:
A
Explanation:
If the object is moving at a constant speed, the object isn't accelerating as the velocity doesn't change.
If the corner is rounded and is perfectly circular, then the acceleration is centripetal and is always directed toward the center.
At the begging nothing is happening, but when you push it, it gains speed that is why the end of a ramp is faster.
