`A` golf ball has a mass of `40g` and a speed of `45m//s`. If the speed can be measured within accuracy of `2%`, calculate the uncertainty in the position.

Explanation

To calculate the uncertainty in the position of a golf ball given its mass and speed, we can follow these steps:

### Step 1: Convert Mass to Kilograms
The mass of the golf ball is given as 40 grams. We need to convert this to kilograms since the standard unit of mass in physics is kilograms.

\[ \text{Mass} = 40 \text{ g} = \frac{40}{1000} \text{ kg} = 0.040 \text{ kg} \]
