Let’s drop a space probe into the m87 black hole.
probe mass is: 10,000 kg
mass of the black hole =6.4 billion times the mass of our sun
probe starts at an infinite distance from the black hole.
if the probe was moving at the speed of light when it hits the event horizon, assuming conservation of energy,
a)determine how close a spaceship could get to the black hole.
hint:
mgh only works on the surface of the earth.
b) according to the minute physics video, how much of the ke would be released
if the black hole was rotating?
give your answer in joule
