What would happen if the difference between the earth and moon decreased? a when the distance decreases the gravitational force increases b the distance decreases so the gravitational force will too c not enough information is known to determine this answer d since the mass of the earth and moon are the same only the weight would change if the distance decreased need on this

A10 kg box initially at rest is pulled 18 meters across a horizontal, frictionless surface by a 40 n force. what is the block’s final velocity over the 18 meters?

1. explain how you calculate the net force in any direction on the box. 2. suppose an upward force of 15n is added to the box. what will be the net vertical force on the box? 3. what force could be applied to the box to make the net force in the horizontal direction zero? explain. 4. suppose a force of 25n to the right is added to the box. what will be the net force to the right?

Acar going 10 m/s starts accelerating at a rate of 3 m/s2 for 4 seconds calculate the final velocity of the car
