Answer:

The period of the satellite is 12.05 s.

Explanation:

The period of the satellite can be determined by;

T = \sqrt{\frac{4\pi ^{2} r^{2}  }{GM} }

where: T is the period, r is the radius of the orbit, G is the gravitation constant and M is the mass of the Earth.

Given that: r = 6 x (6.38 x 10^{6}) = 38.28 x 10^{6} m, M = 5.98 x  10^{24} kg, G = 6.673 x 10^{-11} Nm^{2}/ kg^{2}.

Therefore,

T = \sqrt{\frac{4*(\frac{22}{7} )^{2} (38.28*10^{6}) ^{2}  }{6.673*10^{-11} *5.98*10^{24} } }

  = \sqrt{\frac{5.79*10^{16} }{3.99*10^{14} } }

  = \sqrt{145.113}

  = 12.0463

T = 12.05 s

The period of the satellite is 12.05 s.

an object is thrown into the air with an initial velocity of 12 meters per seconds from a platform that is raised 4 meters above
butalik [34]

Answer:

1.52 seconds

Explanation:

Step 1: identity the given parameters

Initial velocity (u) = 12m/s

Height above ground (h1) = 4m

Final velocity (V) = 0

Step 2: calculate the height travelled by the object from 4m height (h2).

V^2 = U^2 -2gh

0= 12^2-2(9.8*h)

2(9.8*h) = 12^2

19.6*h = 144

h = 144/19.6

h = 7.347 m

Total height above ground (ht) = 4m +7.347m = 11.347m

Step 3: calculate the time reach ground

T = √(2h/g)

T = √(2*11.347/9.8)

T= √(22.694/9.8)

T= √2.316

T= 1.52 seconds
