Newton's **Laws of Motion** | Glenn Research Center | NASA

May 25, 2021 **...** His second **law** defines a **force** to be equal to **change in momentum** (**mass** times **velocity**) per change in time. **Momentum** is defined to be the **mass** m ...

Step 1: know about the change in momentum

Momentum is defined as the mass multiplied by the velocity of any object.

Momentum= mass * velocity

P=mv or \Delta P = \Delta (mv)

Step 2: Fining the final speed of the baseball

Given that

Mass of the baseball m = 0.14 kg

Change in momentum \Delta P = 16 \frac{kg m}{s}

Final speed of the baseball v = ?

\Delta P = mv

16 \frac{kg m}{s} = 0.14 kg * v

v = \frac{16 \frac{kg m}{s}}{0.14 kg}

v = 114.2 m/s

Hence, final velocity of the baseball v = 114.2 m/s
