To calculate the momentum of the billiard ball, we can use the formula:
\[ \text{Momentum} (p) = \text{mass} (m) \times \text{velocity} (v) \]
First, we need to determine the velocity of the ball. The velocity can be calculated using the formula:
\[ \text{Velocity} (v) = \frac{\text{distance}}{\text{time}} \]
Given that the distance is 1.5 m and the time is 0.5 s, we find the velocity:
\[ v = \frac{1.5 , \text{m}}{0.5 , \text{s}} = 3 , \text{m/s} \]
Now we can calculate the momentum:
\[ p = m \times v = 0.180 , \text{kg} \times 3 , \text{m/s} = 0.540 , \text{kg}\cdot\text{m/s} \]
Thus, the momentum of the ball is:
\[ \text{Momentum} = 0.54 , \text{kg}\cdot\text{m/s} \]
So the correct response is:
0.54 kg⋅m/s
