Two ice skaters stand facing each other at rest on a frozen pond. they push off against one another and the 48 kg skater acquires a speed of 0.62 m/s. if the other skater acquires a speed of 0.83 m/s, what is her mass in kilograms?

To solve this problem it is necessary to apply the concepts related to conservation of the moment.

By definition for the particular case we have to,

Where,

Mass first skater

Speed of first skater

Velocity of second skater

Our values are given as,

Replacing in our equation and re-arrange to find

The mass from the second skater is 35.85Kg

the answer to this question is 60 n

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
