A 58-kg ice skater moves across the ice at a constant speed of 2.0 m/s. She is caught by her 69-kg partner, and then the pair continues to glide together. He is at rest when he catches her, and immediately afterward they both coast. Even though the "magnitude of the change in momentum" is requested, you should provide a negative sign if the final momentum is less than (or more negative) than the initial momentum.
a. What is their velocity just after the catch? Assume she moves in the positive x-direction before her partner catches her.
b. A skater follows the girl at a constant speed of 1.0 m/s. What is the magnitude of the girl's change in momentum in the reference frame of the skater?

22. the top of a cliff is located a distance h above the ground. at a distance h/2 there is a branch that juts out from the side of the cliff, and on this branch a bird's nest is located. two children throw stones at the nest with the same initial speed, one stone straight downward from the top of the cliff and the other stone straight upward from the ground. in the absence of air resistance, which stone hits the nest in the least amount of time?
