1. A satellite moves in a circular orbit at a constant speed around the Earth a distance d and the Earth a distance d- 5Rabove the Earth's surface e above the (Earth has a mass M, and radius Ro). For symbolic eyes answers in terms of the variables given and FS a) Sketch a force diagram for the satellite (you may ignore the Sun's force). b) (symbolic) Find the "weight" of the satellite. W = C M, R. (magnitude) c) (symbolie) Find the acceleration of the satellite. a - la ME 162 (magnitude) Sketch the path and acceleration vector. 2. The manager of a department store is pushing initially with a force of ION on a box of mass 5Kg, but it doesn't budge. When she pushes horizontally with a force of magnitude 100 N the box slides across the (unbanked) floor with a constant velocity. a) Sketch a force diagram for the box in both cases. b) Can you find the force of static friction for the initial push of IONAS or no). Can you find the coefficient of static friction for box + floor from this info? (yes or no) c) Can you find the force of kinetic friction for the 100N push? (yes or

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
