Answer to Question #160800 in Physics for Gavin

Question #160800

A 50 kg shell is fired from a cannon on Earth's surface with a potential energy of 196,000 J. What is the shell's maximum height?

Expert's answer

By the definition of the potential energy, we get:

"PE=mgh,""h=\\dfrac{PE}{mg}=\\dfrac{196000\\ J}{50\\ kg\\cdot9.8\\ \\dfrac{m}{s^2}}=400\\ m."
