10. A rock falls from rest a vertical
distance of 0.72 meter to the surface
of a planet in 0.63 second. The
magnitude of the acceleration due to
gravity on the planet is
(1) 1.1 m/s2
(3) 3.6 m/s2
(2) 2.3 m/s2
(4) 9.8 m/s2
1. The population P of elephants in a wild animal preserve changes with time (in years) according to the equation dP - 0.0005P(190 - P)dt = 0. If there are 46 elephants initially, in how many years will the population reach 90?
2. For earth, let g and R be the acceleration due to gravity and the radius, respectively. If another Planet B has one-half the acceleration due to gravity of the earth but four times its radius, then the velocity of escape of that same object placed on Planet B is twice that on earth. (True or False)

Most galaxies, including our own Milky Way, have supermassive black holes at their centers. Recently, astronomers were able to track one star, named S2, as it orbited the black hole at the center of our galaxy. The star's actual orbit is elliptical, but we'll model it as a circular orbit. S2 has a period of 15 years and an orbit radius of 1000 au, where 1 au = 1 astronomical unit is the distance of the earth from the sun. a. What is the speed of S2? Give your answer as a fraction of c, where c is the speed of light, c=3.0×10^8m/s. b. What is the mass of the black hole?
