Un cuerpo que pesa 80 N cae libremente y llega al suelo con una velocidad de 10 m/s: Calcula su energía cinética, Calcula su energía potencial gravitatoria cuando se encuentra a 2 metros de altura.

Explanation:

The question says, "A body that weighs 80 N falls freely and reaches the ground with a speed of 10 m / s: Calculate its kinetic energy, Calculate its gravitational potential energy when it is 2 meters high. "

Weight of a body, W = 80 N

Speed with which it reaches ground, v = 10 m/s

Weight, W = mg

g is acceleration due to gravity and m is mass of the body

Now the kinetic energy of any object is given by :

Potential energy is given by :

We have mg = 80 N and h = 2 m

Hence, this is the required solution.
