How long would it take.... 1. The problem statement, all variables and given/known data This is a problem that followed a bunch of others so I will post what I got for those as well. Here is the problem: How long would it take Kirk to fall to the valley floor? 5.29s or 3.47s or 11.836s or 2.43s or none of those. I am not getting any of them, I don't know if I am doing it correct. I am using the d=1/2gt^2 formula and get 3.645s. Distance being 35.721m and g being 9.8. And that number is not any of the choices listed.... is it non of the above? 2. Relevant equations Captain James T Kirk is on vacation in Ca. He is climbing 59m above the floor of the valley when he stops to rest. Cpt. Kirk has a mass of 110kg. What is the potential energy of Kirk? I got 63602J, using the PE=mgh formula. His kinetic energy would be 0 when he rests. Kirk suddenly looses his grip and begins to fall! How far does he fall in 2.7s? I got 35.721m using d=1/2gt^2 What is Kirks velocity after falling for 2.7s? I got 13.23m/s using the v=d/t formula. What is his kinetic energy after falling for 2.7s? I am not sure about that one, but I got 9626.8095J using the kinetic formula KE=1/2mv^2 What is his potential energy after falling 2.7s? Using the potential energy formula P subscript E =mgh I came up with 38507.238J. Thank you for your time.
