When a star dies, much of its mass may collapse into a single point known as a black hole. The gravitational force of a black hole on surrounding astronomical objects can be very great. Astronomers estimate the strength of this force by observing the orbits of such objects around a black hole. What is the gravitational force exerted by a black hole on a 1-solar-mass star whose orbit has a 1.4 1010 m radius and a period of 5.6 days?

A mass (m) moves along the x-axis in the positive direction with a constant speed vo. At t=0, the mass passes through the origin and is subject to the force F = -Fo(x/H)e^(-x/H) for x >0. Fo and H are both positive constants. %3D a. Calculate the minimum initial speed required for the mass to pass through the origin and never turn back in terms of the constants m, Fo, and H. b.
