As a result of an elastic collision between carts 1 and 2, the kinetic energy of cart 1 doubles. part a how does the kinetic energy of cart 2 change, if cart 1 has the initial energy k1,i = 140 j ? express your answer to two significant digits and include the appropriate units. enter positive value if the energy increases and negative value if the energy decreases.

12000j is work done

increase masses, decrease separation

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

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
