A helicopter moves with a constant velocity v, - 4 m/s from point A to point B during a time interval tas = 10 s. It then accelerates from point B to point C with constant acceleration az =
2m/s2 for a time interval tac = 20 s. The average velocity of this helicopter for the whole trip is
equal to:
A
tas-10
tec-20 s
Q2 = 2m/s2
Di=4 m/s​

if they have a finite resultant

connect the batteries in series and hope

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
