1.12. CHAPTER 1, PROBLEM 12 13 1.12 Chapter 1, Problem 12 Problem: What force is required to impart an acceleration of 1 AU/yr 2 to a 1 kiloslug mass? AU denotes Astronomical Unit ( 93 · 10 6 miles) and yr denotes year ( 365 1 4 days). Solution: Since force ( F ) has units of mass ( M ) times length ( L ) divided by time ( T ) squared, we can say F = ML T 2 So, noting that there are 10 3 slugs in a kiloslug, 93 · 10 6 miles in 1 AU, 5280 feet in a mile, 365 . 25 days

### 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.
