g Michael and John are playing on a seesaw. Michael has a mass of 25 kg and is sitting to the left, 0.4 m from the center of the seesaw, which is also the center of rotation. John has a mass of 40 kg and is sitting to right of the seesaw. At which distance from the center of the Seesaw should John be sitting so the Seesaw will be in rotational equilibrium (No rotation)? use g=9.8m/s2.

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.

not too sure thinking all accelerations are pointed down
