A man stands on the roof of a 18.0-m-tall building and throws a rock with a velocity of magnitude 30.0 m/s at an angle of 37.0 ∘ above the horizontal. You can ignore air resistance. Assume that the rock is thrown from the level of the roof. Calculate the magnitude of the velocity of the rock just before it strikes the ground.

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.
