Calculate the total K.E. of earth, assuming it to be a uniform spherical body moving around the sun with a speed of 30 km s^(-1) and spinning about its own axis? Mass of earth = 6 xx 10^(24) kg,Radius of earth = 6400 km ?

Calculate the total K.E. of earth, assuming it to be a uniform spheric

1.	Calculate the total K.E. of earth, assuming it to be a uniform spherical body moving around the sun with a speed of 30 km s^(-1) and spinning about its own axis? Mass of earth = 6 xx 10^(24) kg,Radius of earth = 6400 km ?
Answer» Solution :Total K.E. `=(1//2) mv^(2) + (1//2) XX (2//5) MR^(2) xx (2pi//T)^(2), T = 24h, K.E. =2.7 xx 10^(33) J`
