To calculate the momentum of the billiard ball, we first need to determine its velocity and then use the formula for momentum.
-
Find the velocity: \[ \text{Velocity} = \frac{\text{Distance}}{\text{Time}} = \frac{1.5 , \text{m}}{0.5 , \text{s}} = 3 , \text{m/s} \]
-
Calculate the momentum: \[ \text{Momentum} = \text{mass} \times \text{velocity} \] \[ \text{Momentum} = 0.180 , \text{kg} \times 3 , \text{m/s} = 0.54 , \text{kg} \cdot \text{m/s} \]
Thus, the momentum of the ball is 0.54 kg⋅m/s.
