Hello everyone, we have given in the question that mass is equals to the mass of solid is square and volume is equals to 32 kg, radius is equals to 0 .25 meter, angle theta is equals to 20 degree, l is equals to 7 degrees length, therefore height is equals to l sin theta, l is 7 and theta is 20 degree, it is sin 20 degree.

Now, this is the figure where we get the value of l, it is the square spherical ball with mass l, l is equals to 7 meter, this is the angle theta, when the ball is here, there is an angular velocity omega and weight becomes omega r.

Now, for the first part of the question, the answer is gravitational potential energy, that is part of the question, we have asked that what type of energy does the object have when it is at the bottom of the rim, the answer is both, kinetic energy t and kinetic energy at r, that is transitional kinetic energy and rotational kinetic energy.

Now, in the third part of the question, we have asked about the moment of inertia of object, when i is equals to moment of inertia of solid square, which is 2 upon 5 m r square, 2 upon 5, m is 32 and r is 0 .25 the whole square, therefore inertia is equals to 0 .8 kg meter square...
