Answer:

The centripetal acceleration is given by a=

v

This expression explicity depends on Moon's speed which i s non trivial . we can work with the formula w

R

m

=a

m

Since,

a

m

→ centrifugal acceleration of the moon due to earth's gravity

w→ angular velocity

R

m

=60R=60×6.4×10

=384×10

m is the distance between earth and the moon, which is 60 times the radius of the earth.

w=

T

angular velocity w=

T

.

and T=27.3days=27.3×24×60×60

Seconds=2.358×10

sec

putting these values in the formula for acceleration

a

m

=

(2.358×10
