During a football game, a receiver has just caught a pass and is standing still. Before he can move, a tackler, running at a velocity of 3.1 m/s, grabs and holds onto him so that they move off together with a velocity of 1.8 m/s. If the mass of the tackler is 115 kg, determine the mass of the receiver in kilograms. Assume momentum is conserved.

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?
