Answer:
v₁ = 1 [m/s].
Explanation:
This problem can be solved by using the principle of conservation of linear momentum. Where momentum is conserved before and after catching the snowball.
where:
P = linear momentum [kg*m/s]
m = mass [kg]
v = velocity [m/s]
As the momentum is conserved, it will be the same as that received by the person who catches the snowball.
That is, the person who catches the snowball moves backwards with a speed of 1 [m/s].
