2.2. In an experiment, a shearwater (a seabird) was taken from its
nest, flown 5150 km away, and released. The bird found its way back
to its nest 13.5 days after release. If we place the origin at the nest and
extend the +x-axis to the release point, what was the bird's average ve-
locity in m/s (a) for the return flight and (b) for the whole episode, from
leaving the nest to returning?

Your blood pressure (usually given in units of "mm of Hg") is a result of the heart muscle pushing on your blood. The left side of the heart creates a pressure of 115 mm Hg by exerting a force directly on the blood over an effective area of 14.5 cm2. What force does it exert to accomplish this? (Give your answer as the number of Newtons and note that you will need to do some unit conversions.)
