A ball of mass 10g is initially moving with a velocity of `50 ms^-1` On applying a constant force a ball for 2.0s, it acquires a velocity of `70 ms^-1` calculate
the initial momentum of ball

Explanation

To find the initial momentum of the ball, we can follow these steps:

### Step 1: Identify the given values
- Mass of the ball (m) = 10 grams
- Initial velocity (V_initial) = 50 m/s

### Step 2: Convert the mass from grams to kilograms
Since the standard unit of mass in physics is kilograms (kg), we need to convert grams to kilograms:
