Calculate the kinetic energy of a body of mass 0.1 kg and momentum 20 kg `ms^(-1)`

Explanation

To calculate the kinetic energy of a body given its mass and momentum, we can follow these steps:

### Step 1: Understand the relationship between momentum and velocity
Momentum (p) is defined as the product of mass (m) and velocity (v):
\[ p = m \cdot v \]
From this, we can express velocity as:
\[ v = \frac{p}{m} \]
