Mischievous joey likes to play with his family's lazy susan (this drives mom crazy because it is an antique). he puts the salt shaker near the edge and tries to spin the tray at a speed so that the shaker just barely goes around without slipping off. joey finds that the shaker just barely stays on when the turntable is making one complete turn every two seconds. joey's older sister measures the mass of the shaker to be 86 grams. she also measures the radius of the turntable to be 0.21 m, and she is able to calculate that the speed of the shaker as it successfully goes around in a circle is 0.6594 m/s.(a)what is the magnitude in newtons of the horizontal part of the contact force on the shaker by the turntable? (b) what is the magnitude in newtons of the vertical part of the contact force on the shaker by the turntable?

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.

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.
