A satellite is put into a circular orbit 200 km above the earth's surface where the acceleration due to
gravity is 9.2 ms 2. Determine (i) satellite's speed
(ii) Time period (time to take one revolution). The
radius of earth is 6400 km

Adiver in midair has an angular velocity of 6.0 rad/s and a moment of inertia of 1.2 kg·m2. he then pulls is arms and legs into a tuck position and his angular velocity increases to 12 rad/s. the net external torque acting on the diver is zero. what is his moment of inertia in the tuck position?
