The range of a projectile depends not onlly on vo and
theta0but also on the value g of the free-fall acceleration, which
variesfrom place to place. in 1936, jesse owens established
aworld's running broad jump record of 8.09 m at the olympic games
atberlin (g = 9.8128 m/s^2). assuming the same values of vo
andtheta0, by how much would his record have differed if he
hadcompeted instead in 1956 at melbourne (g = 9.7999m/s^2)?

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?
