Question

The potential energy of a flying bird is 30.7 J. The kinetic energy of the bird is 128.4 J. What is the bird's Mechanical Energy?

Answer 1

159.1 J

Step-by-step explanation:

Answer 2

we know formula for mechanical energy , E( Mechanical) = U + K , where U is the potential energy and K is the kinetic energy!

So E = 30.7 J + 128.4 J = 159.1 J
