Danielle has a mass of 80 kg and is sitting in a wagon at the top of a 20-m high hill. She slides down. a) How much kinetic energy will she have at the bottom of the hill?

Respuesta :

Answer:

E = 15680 J

Explanation:

We have,

Mass of Danielle is 80 kg

He is at the top of hill at a height of 20 m

As she slides down at the bottom of the hill, its potential energy gets converted to its kinetic energy. So, the kinetic energy at the bottom of the hill is :

[tex]E=mgh\\\\E=80\times 9.8\times 20\\\\E=15680\ J[/tex]

So, she will have 15680 J of kinetic energy at the bottom of the hill.
