Where's my cup of coffee

Climbing out of bed is sometimes hard in the morning. If you have a mass of \(60~\mbox{kg}\), what is the minimum amount of work in joules you have to do to get out of bed? Assume your center of mass when lying in your bed is \(0.75~\mbox{m}\) above the floor, and your center of mass when standing is \(1.25~\mbox{m}\) above the floor.

Details and assumptions

  • The acceleration due to gravity is \(-9.8~\mbox{m/s}^2\).
