a truck starts from rest and accelerates at 4 m/s2 for 9 seconds. how fast will the truck now be going?

why could you accelerate while traveling at a constant speed?

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
