Athin cylindrical rod of length l = 24cm with mass m = 1.2kg has a ball of diameter d=8cm and a mass m = 2kg attached to one end. the arrangement is originally vertical and stationary, with the ball at the top as shown below. the combination is free to pivot about the bottom end of the rod after being given a slight nudge. (a) after the combination rotates through 90 degrees, what is the rotational kinetic energy? (b) what is the angular speed of the ball? (c) what is the linear speed of the center of mass of the ball? (d) how does it compare with the speed had the ball fallen freely through the same distance of 28cm?

Estimate the kinetic energy of the neptune with respect to the sun as the sum of the terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. [assume the neptune is a uniform sphere with mass = 1.0×1026 kg , radius = 2.5×1010 m , rotation period 16.1 h , orbital period 6.01×104 d and is 4.6×109 km from the sun.]
