Question

Try the formula of Centepatal force if it is depend on mass valocity and redious

Answer 1

$\huge{\underline{\underline{\boxed{\sf{\purple{Answer : }}}}}}$

The centripetal acceleration of the moon is v2r. Details of the calculation: (a) The distance the moon travels in 27.3 days is

d = 2πr = 2.41*109 m.

Its speed is v = d/(27.3 days)

= (d/(2.36*106 s))

= 1023 m/s.
