PLEASEEEE HELP The mass of the Earth is 5.98 x1024
kg. The radius of the Earth is 6.37 x 106 m.
Let’s assume his weight with his suit on Earth is 500
pounds.
1)What is Iron Man’s potential energy (in J) at 200 miles
above the Earth’s surface? (Remember, at that height you have
to use .)
Suppose Iron Man’s propulsion system malfunctions and he
finds himself at rest 200 miles above the Earth’s surface.
(That’s a serious malfunction.) At what speed will he strike
the ground? (Hint: you can use conservation of energy,
but the U calculated above was based on U=0 at r=, so you use the same
formula for the potential energy when he strikes the ground, i.e.,
it’s not zero.
What is the impulse when he strikes the
ground?
