![### Physics Momentum Problems
#### (a) Calculate the momentum of a 2000 kg elephant charging a hunter at a speed of 7.50 m/s.
**Solution:**
\[
\text{Momentum} = \text{Mass} \times \text{Velocity}
\]
\[
\text{Momentum} = 2000 \, \text{kg} \times 7.50 \, \text{m/s}
\]
\[
\boxed{\_\_\_\_\_\_\_\_} \text{ kg} \cdot \text{m/s}
\]
#### (b) Compare the elephant's momentum with that of a 0.0400 kg bullet fired at a speed of 600 m/s.
**Solution:**
\[
\text{Momentum of bullet} = 0.0400 \, \text{kg} \times 600 \, \text{m/s}
\]
\[
\boxed{\_\_\_\_\_\_\_\_}
\]
#### (c) What is the momentum in kilograms times meters per second of the 90.0 kg hunter running at 7.00 m/s after missing the elephant?
**Solution:**
\[
\text{Momentum} = \text{Mass} \times \text{Velocity}
\]
\[
\text{Momentum} = 90.0 \, \text{kg} \times 7.00 \, \text{m/s}
\]
\[
\boxed{\_\_\_\_\_\_\_\_} \text{ kg} \cdot \text{m/s}
\]
These exercises help illustrate the concept of momentum, defined as the product of the mass and velocity of an object.
