Danielle cools a 2.0 kg metal object to a temperature of -25.0 °C. She places the metal in 3.0 L of pure water initially at a temperature of 40.0 °C. The final temperature of the mixture is 36.0 °C.
What is the specific heat capacity of the metal? (T/1)

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f
