Not sure about that. Because X is distance between the stars. Doesnt say that its the distance between the center of each star. So i used the radius as well
What did you guys get for the horizontal distance and also for the motor/pully one did you relate the force of friction and force created by the torque of the motor to get the mathematical model
Thats a fat F but i doubt it will happen because they changed the syllabus to get rid of those trivial things and have more analysis type extended responses
