A ball is thrown straight up into the air from the ground with a speed of 10 m/s. What is the maximum height the ball will reach? How much time will it take the ball to fly up and then reach the ground again?

5 m, 2 s

Explanation:

gravity is roughly 10 m/s²downward

That means in one second, the velocity will have been reduced to zero

The average speed is (10 + 0) / 2 = 5 m/s

h = vt = 5(1) = 5 m

It will take as long to fall back to the thrower from rest so total flight is 1 + 1 = 2 s

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.
