Explanation:
Given that,
Altitude 
We need to calculate the radius
Where, R = radius of the earth
h = radius of altitude
Put the value into the formula
(a). We need to calculate the period of the orbit,
Using formula of period
(b). We need to calculate the speed of the satellite
Using formula of speed
Put the value into the formula
(c). We need to calculate the acceleration of the satellite
Using formula of acceleration
Put the value into the formula
Hence, This is the required solution.
Answer:
v = R w
With this expression we see that for each point at different radius the tangential velocity is different
Explanation:
They indicate that the angular velocity is constant, that is
w = dθ / dt
Where θ is the radius swept angle and t the time taken.
The tangential velocity is linear or
v = dx / dt
Where x is the distance traveled in time (t)
In the definition of radians
θ = s / R
Where s is the arc traveled and R the radius vector from the pivot point, if the angle is small the arc (s) and the length (x) are almost equal
θ = x / R
We substitute in the speed equation
v = d (θ R) / dt
The radius is a constant for each point
v = R dθ / dt
v = R w
With this expression we see that for each point at different radius the tangential velocity is different
