Show all work for problem.

3. A shell of mass m = 3.25 kg is launched horizontally with an initial speed of v0 = 385 m/s from a cannon located at the top of a cliff (see Figure), where the height H = 250. m. (Here we ignore air friction). (a) Calculate the kinetic energy of the shell when its vertical height is h = 80.0 and the speed of the shell at that height (h = 80.0 m) KE=
