A kickball is kicked straight up at a speed of 22.4 m/s

Do you mean, how high will it go until it falls back down?

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.

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
