Jack jumped off a diving board and hit the water at 15.68 m/s downward. How long was he falling for before he hit the water?

1.6 s

Explanation:

From the question given above, the following data were:

Velocity (v) = 15.68 m/s

Acceleration due to gravity (g) = 9.8 m/s²

Time (t) =?

Thus, we can calculate the time taken for Jack to hit the water by using the following formula:

v = gt

15.68 = 9.8 × t

Divide both side by 9.8

t = 15.68 / 9.8

t = 1.6 s

Therefore, it took Jack 1.6 s to hit the water.

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.
