A ball is swung in a horizontal circle of centre O with a constant speed. acceleration?
Answer Details
When a ball is swung in a horizontal circle with a constant speed, it experiences a centripetal acceleration directed towards the center of the circle. The centripetal acceleration is the acceleration required to keep an object moving in a circular path, and it is given by the formula:
a = v\(^{2}\) / r
where v is the speed of the ball and r is the radius of the circle.
In this case, the ball is moving in a horizontal circle, so the centripetal acceleration acts vertically towards the center of the circle (O).
So, the acceleration of the ball is toward the center O.
