Question

The Moon orbits the Earth once in 27.3 days in almost circular orbit. Calculate the centripetal acceleration experienced by the Earth. (Radius of the Earth is 6.4×10^6m)​

Answer 1

Answer:

2.7 x 10–3 m/s²

Explanation:

In order to keep an object going around in a circle, that object must be pulled toward the center of the circle. Take a look at the Moon circling Earth in the following figure. The Moon is accelerated toward Earth along a radius from Earth to the Moon.
