Lizzy Cole is lounging on a raft (initially at rest) in the middle of her pool. She is minding her own business, reading her .55 kg physics book, when Trace thought it would be funny to dump a bucket of water on her. Lizzy, attempting some kind of revenge, chucks her physics book at Trace with a velocity of 3.7 m/s. a. If the raft and Lizzy weigh 620 N, at what velocity does Lizzy and her raft move immediately after the book is thrown? (Note: Lizzy and the raft will move in the opposite direction of the book.)
b. If Lizzy is 2.4 m from the edge of the pool how long does Trace have to run before she reaches the edge?

Which of these statements best explains how the hydrosphere interacts with the atmosphere to affect global climate? mountains block rain clouds and cause changes in global rainfall and evaporation. humans burn fossil fuels to produce greenhouse gases which cause global warming. humans cut down trees which affects the amount of oxygen in different parts of the globe. greenhouse gases, like carbon dioxide, dissolve in oceans and prevent global warming.
