An Elf Ranger is firing their bow at the evil wizard's spellbook in their hand at rest. The arrow embeds itself in the book and book and arrow together leave the wizards hand with some horizontal speed and fall a distance 2 m away. If the wizard had their spellbook at 1.3 m in the air when the arrow struck it and its mass is 1.5 kg, how fast was the 0.10 kg arrow moving before it hit the book? 93 m/s 110 m/s 42 m/s 82 m/s
