Question

A meteorite of mass 700 gm fell on earth from a height of 1000 km from the earth surface. How much energy is expelled on impact considering that all the energy is transferred to the earth. (g=9.8 m/s^2). (Ignore Air resistance)

Answer 1

Answer:-

Explanation:-

We know that potential energy is give by,

E=mgh

Where m= mass of the body in kg

g= Earth's gravitational force in m/s²

h= Height in meters

E=0.7*9.8*1000000

=6860000joules

Answer 2

Answer:v . 7.3498
