Answer:
The velocity will be v1 = 0.58[m/s]
Explanation:
This problem can be solved by the law of conservation of the moment, which explains that the moment of a system remains constant because there are no external forces acting on it.
We have the following initial data:
m1 = mass of the skater = 55 [kg]
m2 = mass of the ball = 3 [kg]
v2 = velocity of the ball = 8 [m/s]
Therefore:
![m_{1}*v_{1}+m_{2}*v_{2}=m_{1}*v_{1}+m_{2}*v_{2}\\(50*0)+(3*0)=(50*v_{1})+(3*8)\\50+3-24=50*v_{1}\\v_{1}= 0.58[m/s]](https://tex.z-dn.net/?f=m_%7B1%7D%2Av_%7B1%7D%2Bm_%7B2%7D%2Av_%7B2%7D%3Dm_%7B1%7D%2Av_%7B1%7D%2Bm_%7B2%7D%2Av_%7B2%7D%5C%5C%2850%2A0%29%2B%283%2A0%29%3D%2850%2Av_%7B1%7D%29%2B%283%2A8%29%5C%5C50%2B3-24%3D50%2Av_%7B1%7D%5C%5Cv_%7B1%7D%3D%200.58%5Bm%2Fs%5D)

The accuracy of a series of measurements is best understood by looking at the known value.
The values obtained in a series of measurement can be precise or accurate.
The precision of the measurement is obtained by looking at the trend of the values obtained.
- If the values are close to each other, the measurement is precise but if the values are far from each other, the measurement is not precise.
The accuracy of a measurement is determine by comparing the determine value against a known value.
- If the measured value is close to a <em>known value</em>, then the measurement is accurate, but if the measured value is from from a known value then the measurement is not accurate.
Thus, the accuracy of a series of measurements is best understood by looking at the known value.
