Understanding Momentum

The Formula for Momentum

The formula for momentum is given by:

p = mv

where p is the momentum, m is the mass of the object, and v is its velocity.

Calculating the Momentum of a Speedboat

Suppose a $$1,500 , \text{kg}$$ speedboat is traveling with a velocity of $$13 , \text{m/s}$$. To calculate the speedboat's momentum, we can use the formula above.

Step 1: Identify the Given Values

Mass of the speedboat: $$1,500 , \text{kg}$$
Velocity of the speedboat: $$13 , \text{m/s}$$

Step 2: Plug in the Values into the Formula

Using the formula p = mv, we can plug in the given values:

p = (1,500 kg) × (13 m/s)

Step 3: Calculate the Momentum

To calculate the momentum, we multiply the mass and velocity:

p = 19,500 kg·m/s

Answer: The Speedboat's Momentum is 19,500 kg·m/s

Therefore, the speedboat's momentum is 19,500 kg·m/s.

Comparison with the Given Options

Let's compare our calculated value with the given options:

A. $115 \, \text{kg} \cdot \frac{\text{m}}{\text{s}}$
B. $1,513 \, \text{kg} \cdot \frac{\text{m}}{\text{s}}$

Our calculated value, 19,500 kg·m/s, does not match either of the given options. This suggests that the options provided are incorrect.

Conclusion

In this example, we calculated the momentum of a speedboat using the formula p = mv. We found that the speedboat's momentum is 19,500 kg·m/s, which does not match the given options. This highlights the importance of understanding the concept of momentum and using the correct formula to calculate it.
