Answer:
(d) 0.07 m/s
Explanation:
Given Data
Snowball mass m₁=0.15 kg
Ice skater mass m₂=65.0 kg
Snowball velocity v₁=32.0 m/s
To find
Velocity of Skater v₂=?
Solution
From law of conservation of momentum
![m_{1}v_{1}=m_{2}v_{2}\\ v_{2}=\frac{m_{1}v_{1}}{m_{2}}\\ v_{2}=\frac{(0.15kg)(32.0m/s)}{65.0kg}\\ v_{2}=0.0738m/s\\or\\v_{2}=0.07 m/s](https://tex.z-dn.net/?f=m_%7B1%7Dv_%7B1%7D%3Dm_%7B2%7Dv_%7B2%7D%5C%5C%20%20v_%7B2%7D%3D%5Cfrac%7Bm_%7B1%7Dv_%7B1%7D%7D%7Bm_%7B2%7D%7D%5C%5C%20v_%7B2%7D%3D%5Cfrac%7B%280.15kg%29%2832.0m%2Fs%29%7D%7B65.0kg%7D%5C%5C%20v_%7B2%7D%3D0.0738m%2Fs%5C%5Cor%5C%5Cv_%7B2%7D%3D0.07%20m%2Fs)
So Option d is correct one

c. dioptre that's the answer.
In the 1970, the average American ate only 2 pounds of sugar a year. In 1970, we ate 123 pounds of sugar per year. Today, the average American consumes almost 152 pounds of sugar in one year. This is equal to 3 pounds (or 6 cups) of sugar consumed in one week!
