6.Calculate the centripetal acceleration of the Earth towards the Sun. (r = 1.5 x 1011 m) I'm not really sure about this problem so I need some help

Given,

The radius of Sun,

To find,

The centripetal acceleration of the Earth towards the Sun.

Solution,

The centripetal acceleration of an object is given by the formula as follows :

....(1)

Where

is angular velocity

First calculate the angular velocity.

Put all the values in formula (1)

So, the centripetal acceleration of the Earth towards the Sun is .

it is called kinetic energy
