The moon's orbital and rotational periods are identical or the same, I<span>ts rate of spin is done in unison with its rate of revolution (the time that is needed to complete one orbit). Thus, the moon rotates exactly once every time it circles the Earth.</span>
centripetal acceleration is given by formula

given that


now we have




so the ratationa frequency is given by




I need pictures or something
Speed v = initial speed u + acceleration a x time t
v=u+at = 2 + 4*3 = 14 m/s
