A rod of length 2 m is held vertically with one of its end on the floor. It is then allowed to fall. Calculate the speed of the other end when it strikes the floor. Assume that the end of the rod which is on the floor does not slip.

Explanation

To solve the problem of finding the speed of the other end of a falling rod when it strikes the floor, we can follow these steps:

### Step 1: Understand the System
The rod is 2 meters long and is pivoted at one end on the floor. When it falls, it rotates about the pivot point (the end on the floor).

### Step 2: Identify Energy Conservation
We will use the principle of conservation of energy. The potential energy (PE) of the rod when it is vertical will be converted into rotational kinetic energy (KE) when it strikes the floor.
