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

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
