Two objects are placed 3 meters apart. If they were moved, at what distance would the NEW gravitational force be about 1/4 of the original value? 1.5 meters (1/2 the distance)
6 meters (twice the distance)
3/4 meters (1/4 the distance)
12 meters (4 times the distance)

You want to move a heavy box with mass 30.0 kg across a carpeted floor. you pull hard on one of the edges of the box at an angle 30∘ above the horizontal with a force of magnitude 240 n, causing the box to move horizontally. the force of friction between the moving box and the floor has magnitude 41.5 n . what is the box's acceleration just after it begins to move
