A stone with mass m = 2.3 kg is thrown vertically upward into the air with an initial kinetic energy of 190 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 2.3 N. What is the maximum height reached by the stone?
What is the speed of the stone upon impact with the ground?

2.3
