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

answer: a. same unit

explanation:
