Evaluate the accleration of a satillite travelling at a constant speed of 7000m/s in circular orbit of radius of 3000km.
a)15.33m/s2
b)16.33m/s2
c)1.633m/s2
d)17.33m/s2
Let 'a't
and 'a'nbe tangential and normal components
of accleration respectively,
at = dv/dt and an = v2/r
and r is the radius of rotation.
Since the object
is moving at constant speed impling that the rate of change of tangential
velocity is zero and dv/dt=0
and at =0.
Normal accleration:
an =(7000)2/3000x103=16.33m/s2
a = an =
16.33 m/s2.
So, the accleration of the satillite a = 16.33 m/s2
