Question

Find out energy required in gigajoule to escape a space shuttle of 1000 kilogram mass from the surface of earth

Answer 1

Answer:

6.27 GJ

Step By Step Explanation:

The energy required to escape a shuttle from the surface of the Earth is equal to the Potential Energy.

Potential energy is calculated as: P = mgh; where m is the mass of the space shuttle, g is the gravitational force of acceleration and h is the height, which in this case is the radius of the Earth.

N.B: $g=9.8\:m/sec^2\\h=6400\:km$

Therefore,$P=1000*9.8*6400*10^3=6.27\:GJ$
