The answer is the second option, or 1/10 the same momentum.
A 10 kg ball is travelling at the same speed as a 1 kg ball. It has 1/10 the momentum when compared to the 10 kg ball
Answer: Option 2
Explanation:
If two objects travel with same speed, then the momentum can be calculated by the following,
Consider mass of 1 kg ball is [tex]m_{1}[/tex]
for 10 kg ball as [tex]m_{2}[/tex]
Velocity is same for both so it is v
Momentum, [tex]p=mass \times velocity[/tex]
Then, [tex]p_{1}=1 \times v=v[/tex]
[tex]p_{2}=10 \times v=10 v[/tex]
When substituting for v as [tex]p_{1}[/tex], we get [tex]p_{2}=10 p_{1}[/tex]
[tex]p_{1}=\frac{1}{10} p_{2}[/tex]
From this, we know momentum of 1 kg ball is 1/10 times that of 10 kg ball.
