(b)
v = 13.74 km/s
(c) E = 0.28 N/kg
Explanation:
Time period, T = 3.55 days = 3.55 x 24 x 3600 second = 306720 s
Radius, r = 6.71 x 10^8 m
G = 6.67 x 10^-11 Nm^2/kg^2
(a)
M = 1.898 x 10^27 kg
(b) Let v be the orbital velocity
v = 13739.5 m/s
v = 13.74 km/s
(b) The gravitational field E is given by
E = 0.28 N/kg
Answer:
a)
b) T = 720.85N
Explanation:
With a balance of energy from the lowest point to its maximum height:
Solving for :
Centripetal acceleration is:
To calculate the tension of the rope, we make a sum of forces:
Solving for T:
T = 720.85N
