Question

A spacecraft is in orbit close to the moon's surface. The centripetal acceleration is  1.6 m/s^2. If the radius of the moon is about 1.7 x 10^6 m, determine:
a)the orbital speed
b)the period of the orbit

bobpursley · Answer

v^2/r=1.6 m/s^2 find v then, period v=distance/period period=2PI*r/v
