3) In the figure below, a ball is thrown from point A on top of an inclined plane of = 57°, with an initial velocity V0 and an angle . The ball takes 1.25 seconds to reach the maximum height of its trajectory (point B) and at this moment it is at a horizontal distance D = 3.7 m from the launch point. For this situation, calculate (a) the launch angle; (b) the initial velocity V0; (c) the total flight time between points A and C; (d) the velocity of the ball at the instant it reaches point C; and (e) the distance D between the launch point and the impact point. Tip: use the relationship sen(a)/cos(a)=tg(a)

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2

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?
