Astronomers using the Hubble Space Telescope deduced the presence of an extremely massive core in the distant galaxy M87, so dense that it could be a black hole (from which no light escapes). They did this by measuring the speed of gas clouds orbiting the core to be 790 km/s at a distance of 60 light-years (=5.7ร10ห17m) from the core.
a.)Deduce the mass of the core.
b.)compare it to the mass of out sun

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius ํ
=0.381meters and mass ํ=3.1ํํ. initially ํ"is on the ground and ํ#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of ํ#just before it strikes the ground. assume the pulley bearing is frictionless.
