An object is placed in a fluid and then released. assume that the object either floats to the surface (settling so that the object is partly above and partly below the fluid surface) or sinks to the bottom. (note that for parts a through d, you should assume that the object has settled in equilibrium.)

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

The slope of a velocity time graph over any interval of time gives the during that interval

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?
