At stone is tied to the end of a string ...

At stone is tied to the end of a string and is whirled in a horizontal aide with a constant speed. Suppose the string breaks suddenly. What happens to the stone ?

Text Solution

AI Generated Solution

To solve the problem of what happens to the stone when the string breaks, we will analyze the situation step by step. ### Step-by-Step Solution: 1. **Understanding Circular Motion**: - The stone is initially moving in a circular path due to the tension in the string, which provides the necessary centripetal force to keep it moving in that circular motion. 2. **Direction of Velocity**: ...
