Answer:
![6.5\%\ of\ u_1](https://tex.z-dn.net/?f=6.5%5C%25%5C%20of%5C%20u_1)
Explanation:
= Mass of ball = 0.12 kg
tex]m_{2}[/tex] = Mass of bottle = 2.4 kg
= Initial velocity of ball
= Initial velocity of bottle
= Final velocity of ball = ![-0.3u_{1}](https://tex.z-dn.net/?f=-0.3u_%7B1%7D)
= Final velocity of bottle
As linear momentum is conserved
![m_{1}u_{1}+m_{2}u_{2}=m_{1}v_{1}+m_{2}v_{2}\\\Rightarrow 0.12u_{1}+2.4\times 0=-0.12(0.3u_{1})+2.4v_{2}\\\Rightarrow 0.156u_1=2.4v_2\\\Rightarrow \frac{v_2}{u_1}=0.065\\\Rightarrow v_2=0.065\times 100\times u_1\\\Rightarrow v_2=6.5\%\ of\ u_1](https://tex.z-dn.net/?f=m_%7B1%7Du_%7B1%7D%2Bm_%7B2%7Du_%7B2%7D%3Dm_%7B1%7Dv_%7B1%7D%2Bm_%7B2%7Dv_%7B2%7D%5C%5C%5CRightarrow%200.12u_%7B1%7D%2B2.4%5Ctimes%200%3D-0.12%280.3u_%7B1%7D%29%2B2.4v_%7B2%7D%5C%5C%5CRightarrow%200.156u_1%3D2.4v_2%5C%5C%5CRightarrow%20%5Cfrac%7Bv_2%7D%7Bu_1%7D%3D0.065%5C%5C%5CRightarrow%20v_2%3D0.065%5Ctimes%20100%5Ctimes%20u_1%5C%5C%5CRightarrow%20v_2%3D6.5%5C%25%5C%20of%5C%20u_1)
The bottle's speed is ![6.5\%\ of\ u_1](https://tex.z-dn.net/?f=6.5%5C%25%5C%20of%5C%20u_1)
