To determine the momentum of Ball 1 after the collision, we need to analyze the situation using the principle of conservation of momentum.
Assuming this is a completely elastic collision and that Ball 2 is initially stationary, we can use the following conservation of momentum formula:
\[ \text{Total initial momentum} = \text{Total final momentum} \]
Let:
- \( p_{1i} \) = initial momentum of Ball 1 = 10 kg m/s (before collision)
- \( p_{2i} \) = initial momentum of Ball 2 = 0 kg m/s (before collision)
So, the total initial momentum \( p_{\text{initial}} \) is: \[ p_{\text{initial}} = p_{1i} + p_{2i} = 10 + 0 = 10 \text{ kg m/s} \]
Now, after the collision, let:
- \( p_{1f} \) = final momentum of Ball 1
- \( p_{2f} \) = final momentum of Ball 2
Using conservation of momentum: \[ p_{\text{initial}} = p_{1f} + p_{2f} \]
Since we are not provided with more information about the mass and velocities of Ball 2, or the type of collision (elastic or inelastic), we cannot simply deduce the post-collision momentum of Ball 1 from the given options without additional information.
If the question is asking for specific information about the post-collision momentum of Ball 1, it is likely assuming that Ball 1 loses a certain amount of momentum to Ball 2.
However, the answer cannot be definitively calculated without knowing the specific details of the collision. Could you provide any additional information on the type of collision or mass of the balls?
