A hammer of mass `500g`, moving at `50m//s`, strikes a nail. The nail stops the hammer in a very short time of `0.01 s`. What is the force of the nail on the hammer?

Explanation

To solve the problem, we will follow these steps:

### Step 1: Convert the mass of the hammer to kilograms
The mass of the hammer is given as 500 grams. We need to convert this to kilograms because the standard unit of mass in physics is kilograms.

\[ \text{Mass (m)} = 500 \text{ g} = \frac{500}{1000} \text{ kg} = 0.5 \text{ kg} \]
