Question

2 the table below describes the motion of balls x and y. which of the following best describes the momentum of each ball? a balls x and y have the same momentum because they have the same mass b balls x and y have the same momentum because they have the same inertia c ball y has a greater momentum than ball x because it has zero velocity d ball x has a greater momentum than ball y because it has a greater velocity

Explanation:

Step1: Recall momentum formula

The formula for momentum is $p = mv$, where $p$ is momentum, $m$ is mass and $v$ is velocity.

Step2: Calculate momentum of Ball X

For Ball X, $m = 0.17$ kg and $v=0.5$ m/s. So $p_X=0.17\times0.5 = 0.085$ kg·m/s.

Step3: Calculate momentum of Ball Y

For Ball Y, $m = 0.17$ kg and $v = 0.0$ m/s. So $p_Y=0.17\times0.0=0$ kg·m/s.

Step4: Compare momentums

Since $0.085>0$, Ball X has a greater momentum than Ball Y because it has a greater velocity.

Answer:

D. Ball X has a greater momentum than Ball Y because it has a greater velocity
