1. The problem statement, all variables and given/known data A stone with mass m = 1.8 kg is thrown vertically upward into the air with an initial kinetic energy of 310 J. The drag force acting on the stone throughout its flight is constant, independent of the velocity of the stone, and has a magnitude of 2.5 N. (a) What is the maximum height reached by the stone? (b) What is the speed of the stone upon impact with the ground? 2. Relevant equations 3. The attempt at a solution This one completely confused me and I am not sure how to solve it. Any help would be greatly appreciated. Thanks.
