Textbook Question

Chapter 12, Problem 59PCE

The magnitude of the tidal force exerted on a linear object of mass m and length L is approximately 2GmML/r³. In this expression, M is the mass of the body causing the tidal force and r is the distance from the center of m to the center of M. Suppose you are 1 million miles (1.6 × 10⁹ m) away from a black hole whose mass is 1.99 × 10³⁶ kg (one million times that of the Sun). (a) Estimate the tidal force exerted on your body (L = 1.8 m) by the black hole. (b) At what distance will the tidal force be approximately 10 times greater than your weight?

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.)
