While you are sitting on a chair at the edge of a 1.8-m-deep swimming pool, your eyes are 1.4 mabove the surface of the water. You see an acorn on the bottom of the pool at a 45? angle below the horizontal.
What is the horizontal distance between you and the acorn?
d =

d=2.55m

Explanation:

This is a right angle triangle opp/ hyp = sin45

1.8/d = sin45

d sin45=1.8

d= 1.8/sin 45= 1.8/0.7071 = 2.55m

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
