an eagle has a mass of 8 kg and is flying 85 m above he ground with a speed of 20 m/s. what is the total mechanical energy of the eagle
Answer:
8264 Joules
Explanation:
Mechanical Energy (ME) = Kinetic Energy (KE) + Gravitational Potential Energy (GPE)
Kinetic Energy = (0.5massvelocity^2)
Gravitational Potential Energy = (massheight9.8)
Note: The 9.8 in the GPE formula is Earth's gravity, it will be different on different planets.
ME = (0.5820^2) + (8859.8) = 8264
Substitute values into the variables, then put into calculator and solve.
