Question 1 2 pts What is the gravitational potential energy of a system containing a passenger jet that weighs 7'105 N (fully loaded) when the jet reaches its cruising altitude of 10 km? Enter potential energy in scientific notation X 10^ Joules (just ONE significant figure) Question 2 1 pts How many joules of work were done to lift the jet plane in the previous question to that altitude? Explain.p O words > Question 3 3 pts How much work must be done to stop a steel ball with a mass of 4.0 kg rolling across a surface at a speed of 62 m/s? Enter the sign of the work (positive or negative) Enter the energy in scientific notation (no sign, two significant figures) X 10^ JoulesQuestion 5 2 pts Potential Energy A 25.0-kg shell is shot from a cannon at Earth's surface. The reference level is Earth's surface. a. What is the shell-Earth system's gravitational potential energy when the shell's height is 425 m? b. What is the change in potential energy when the shell falls to a height of 225 m? Show all work and units for full credit. Part B is the change of potential energy from 425 m to 225 m.
