Calculations

Conclusion

Given: Superman's mass=101kg

Acceleration of gravity=9.8m/s/s

In order for the falling body to hit the ground at terminal velocity, the Green Lantern must launch it into the air at its terminal velocity. From a height of 89.777 meters (295 feet), the body would reach a falling speed of 41.948 meters per second (93.8 mi/h).

Green Lanterns' Powers

The Power Ring:

telekinesis

manipulation of fundamental forces

energy/matter construction

flight

force field generation

replication of energy waves (important)

awesomeness

et cetera

Period 2

Earth's Green Lantern and Superman enter a quarrel about who has super-heroic jurisdiction over sector 2814 (including Earth). In order to solve this dispute, the two engage in non-lethal combat.

First, Green Lantern emits a radioactive frequency mimicking Kryptonite, Superman's main weakness, preventing the man of steel's flight and various other abilities.

Question: From how high must Superman fall so he hits the ground at terminal velocity?

F(g)=m*a=9.8*101

K=.5mv^2

Terminal Velocity= (2mg)/((rho)(A)(C ))

rho=air density=1kg/m^3

A=surface area=.75m^2

C =drag coefficient=1.5

The Green Lantern will now keep the earth safe.
