Question:
A rock of mass m is tied to a string of length L and swung in a horizontal circle of radius r. The string can withstand a maximum tension Tmax before it breaks.
(a) What is the maximum speed vmax the rock can have without the string breaking?
(b) The speed of the rock is now increased to 3vmax. The original single string is then replaced by N pieces that are all identical to the original string. What is the minimum value of N required so that the strings do not break? Ignore the force of gravity on the rock.
Step by Step Answer:
Since the rock is moving in a horizontal circle the tension must provide a force equal to its mass t...View the full answer

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
