Aprojectile is fired straight upward from earths surface with a speed c given by: v^2= gm/2r. where m is the mass and r is the radius. the farthest the projectile reaches from the center of the earth is: 2r
5r/4
infinity
4r
4r/3

4R/3

Explanation:

r = Distance from the surface of the Earth

R = Radius of Earth

G = Gravitational constant

M = Mass of Earth

m = Mass of satellite

v²= GM/2R

Loss of Kinetic energy is equal to Gain in potential energy

∴ The farthest the projectile reaches from the center of the earth is

i'm on my way to history not a mistory.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
