...until the coefficient of? static friction was 0.000000001. The girls could not walk or stand up on the ice and were stranded. Sarah pulled a physics book out of her bag and came up with the idea that Michelle could throw the book as hard as possible and use the conservation of momentum to save them. Michelle thought this over and decided they should head south. Michelle has a mass of 86.13kg and Sarah has a mass of 11.6 kg. The book has a mass 0f 2.48kg. The velocity with which Michelle can throw the book is 19.02 M/s. The distance to shore is 3437.1M. In what direction should Michelle throw the book? If Michelle holds Sarah on her lap and throws the book what will their velocity be as they slide towards shore? How long will it take them to reach shore? What is the kinetic energy of the girls? What is the kinetic energy of the book? Please help explain how to do this to me I am completely puzzled as to how to start. Thank You!
