A 5g bullet moving at 600m/s penetrates a tree trunk to a depth of 4cm.(a)Use the work energy theorem, to determine the average frictional force that stops the bullet.(b)Assuming that the frictional force is constant, determine how much time elapses between the moment the bullet enters the tree and the moment it stops moving.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
