Objects 1 and 2 attract each other with a electrostatic force of 72.0 units. If the distance separating Objects 1 and 2 is

changed to four times the original value (i. e., quadrupled),

then the new electrostatic force will be units.

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?
