Two tug boats push on a barge in a bay with mass 61,014kg as seen in the picture below. If one barge pushes east with a force of F1 = 50,597N, one
pushes north with a force of F2 = 32,351N and the third pushes at an angle of
35 degrees above the horizontal with a force of 12,000N. Find the resulting
acceleration of the boat

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
