Two people, one with mass m1 and the other with mass m2, stand on a stationary sled with mass m on a frozen lake. assume that the ice is frictionless. a) the first person (with mass m1) jumps off the sled with a velocity −sxˆ relative to the (stationary) sled. what is his velocity? use conservation of momentum to find the velocity of the sled (which is still carrying the second person).

Explanation:

As we know that if there is no any external force on the system then the linear  momentum of system will remain conserve.

Linear momentum P= m .v

If F(net) = 0

Given that velocity of first person is s .

Form conservation of momentum

Let V is the final velocity

Initial momentum =

Final momentum =
