Problem: You see a pair of shoes tied together by the laces and hanging over a telephone line. You throw a 0.18-kg stone at one of the shoes (mass = 0.39 kg), and it collides elastically with the shoe with a velocity of 1.9 m/s in the horizontal direction.
Part A: How far up does the shoe move?
I need help to determine how far up does the shoe move.
