## Homework Statement

Two 21.0 kg ice sleds are placed a short distance apart, one directly behind the other, as shown in the figure. A 3.41 kg cat, initially standing on sled 1, jumps across to sled 2 and then jumps back to sled 1. Both jumps are made at a horizontal speed of 4.04 m/s relative to the ice. What is the final speed of sled 2? (Assume the ice is frictionless.)

## Homework Equations

## The Attempt at a Solution

(mass of cat + mass of sled)*(horizontal speed of cat) = (mass of sled)*(final speed of sled 2) - (mass of cat)*(speed of cat with respect to ground)

-- how do i find the speed of cat with respect to ground
