Asolid disk has a mass of 162 kg and a radius of 1.30m. this
disk rotates about an axis through its center, like acompact discl
and has an angulaar speed of 18.0 rad/s. if allthe kinetic energy
of this disk were used to lift a 3.00 kg block, how high could the
block be lifted?

Acrow drops a 0.11kg clam onto a rocky beach from a height of 9.8m. what is the kinetic energy of the clam when it is 5.0m above the ground? what is its speed at that point?

In a simplified model of the human eye, the aqueous and vitreous humors and the lens all have a refractive index of 1.40, and all the refraction occurs at the cornea, whose vertex is 2.60 cm from the retina. what should be the radius of curvature of the cornea such that the image of an object 40.0 cm from the cornea’s vertex is focused on the retina?

Four 5-gram blocks of metal are sitting out in the sun and absorb the same amount of heat energy. use the following specific heat capacity data to determine which block will increase its temperature the most.
