Calculate the angular velocity of earth about its own axis.

In order to make the effective acceleration due to gravity at the equator to zero, the numerical value of the angular velocity of rotation of the earth should be [Radius of the earth=6400 km, g=10m/s^(2) ]

Show on a diagram the vector that would represent the angular velocity of the earth rotating about its axis.

The speed of earth's rotation about its axis is omega . Its speed is increased to x times to make the effective accel acceleration due to gravity equal to zero at the equator, then x is around (g= 10 ms^(-2) R = 6400 km)

Calculate the centripetal acceleation of a point on the equator of earth due to the rotatin of earth about its wn axis . Radius of earth = 6400 km .

The angular velocity of a body rotating about a given axis is doubled. Its kinetic energy
