A ball rolls from x = 10 m to
x= -25 m in 2.5 seconds. What was
its average velocity?
(Units = m/s)
Don't forget: velocities and displacements to
the right are +, to the left are -

Much of the information taught in earth-space science would not be available if it weren’t for our remote sensing abilities. explain two ways our remote sensing strategies contribute to our knowledge of these topics.
