A ball in thrown vertically up. D is the highest point the ball reached. Find the ratio of KE at B to the PE at C.

**Solutions: 1 : 1**

To solve such question, you have to apply **conservation of energy**. In other words, **total energy **of ball at any positions (A, B, C and D) is the **same** (no air resistance etc). There is no way to find KE as no speed is given. So to find KE, you need to find it indirectly with the help of PE.

Understand the concept here as there can be many variations of question asked.
