Question

please answer question number 2.

lit pernod of any object orbiting the Sun and r is its average distance trom the Sun. If the period of an asteroid is 600 days, what is its average distance from the Sun? Note Msun-2.0x1030 kg 7er r= (9,645) 2) A satellite whose mass is 50.0 kg is moving in a stable circular orbit 95 km above the surface of the Moon. Assume that the radius of the Earth i kg, the mass M(Moon)-735x1022 kg and R(Moon)=1.74x106 m. G-667x10-11 NmWkg2 a. Compute the speed of the satellite. h)-638x106 m, the mass M(Earth)-5,8x1024 b. Compute the period of the satellite. c. Compute the force acting on the satellite at that height. 3) A 63.0 kg woman is on a spring scale in an elevator. a. What does it read (in N) if the elevator is at rest? b. Now the elevator accelerates and the scale says 550 N. What is the accleration of the elevator? or accelerates am3(9 Siaa.l-2,73(125mls

Explanation / Answer

In the circular orbit

gravitational force Fg = G*Ms*ME/(RE+h)^2

RE = radius of earth

ME = Mass of earth

centripetal force Fc = Ms*V^2/(RE + h)

Fc = Fg

Ms*V^2/(RE+h) = G*Ms*ME/(RE + h)^2

V = sqrt(G*ME/(RE+h))

v = sqrt(6.67*10^-11*5.98*10^24/(6.38*10^6 + 95000))

v = 7848.62 m/s

=================

b)

tiem period T = 2*pi*(RE+h)/v

T = 2*pi*(6.38*10^6 + 95000)/7848.62

T = 5183.5 s

================

c)

Force = Fg = 6.67*10^-11*50*5.98*10^24/(6.38*10^6 + 95000)^2

Force = 475.68 N
