Halliday, Resnick & Walker β Potential Energy and Conservation of Energy: Problem 51_E
During a rockslide, a 520 kg rock slides from rest down a hillside that is 500 m long and 300 m high. The coefficient of kinetic friction between the rock and the hill surface is 0.25. (a) If the gravitational potential energy \( U \) of the rockβEarth system is zero at the bottom of the hill, what is the value of \( U \) just before the slide? (b) How much energy is transferred to thermal energy during the slide? (c) What is the kinetic energy of the rock as it reaches the bottom of the hill? (d) What is its speed then?
