Chapter 5, Problem 1PC

Calculate the momentum of a $10-\text{kg}$ bowling ball rolling at $3\text{m}/\text{s}$.

To determine

The momentum of the bowling ball.

Answer to Problem 1PC

The momentum of the bowling ball is $30\text{kg}\cdot \text{m}/\text{s}$.

Explanation of Solution

Given Info: The mass of the bowling ball is $10\text{kg}$ and rolling speed of the bowling ball is $W$.

Write the expression for momentum of the bowling ball.

$P=mv$

Here,

$P$ is the momentum of the bowling ball

$m$ is the mass of the bowling ball

$v$ is the rolling speed of the bowling ball

Substitute $10\text{kg}$ for $m$ and $3\text{m}/\text{s}$ for $v$ in the above expression to find $P$.

$\begin{array}{c}P=\left(10\text{kg}\right)\left(3\text{m}/\text{s}\right)\\ =30\text{kg}\cdot \text{m}/\text{s}\end{array}$

Conclusion:

Therefore, the momentum of the bowling ball is $30\text{kg}\cdot \text{m}/\text{s}$.
