Question

Or
To explain centripetal acceleration and centripetal force. The man complete one round around
the earth in 27 day 7 hrs. If radius of the moon is 3.85 x 108 m. Find acceleration.​

Answer 1

Answer:

This is the acceleration of moon with respect to Earth.

Explanation:

Distance between Earth and Moon

r =3.85×10⁵

km =3.85×10⁸m

T = 27.3days = 24×3600×(27.3)sec = 2.36×10⁸sec

Time period of the moon will be

T = 2πr/v

v = 2π×3.85×10⁸/27.3×24×60×60

=1025.98m/s

The acceleration of the moon is,

a= v²/r

a= (1025.98)²/3.85×10⁸

=2.73×10−³ m/s²
