calculate ine gravitational potential energy of the ball using pe=m×g×h.(use g=9.8 n/kg)


A 4.0-kilogram ball held 1.5 meters above the floor has ________ joules of potential energy​

Respuesta :

quasarJose

Answer:

58.8J

Explanation:

Given parameters;

Mass of ball  = 4kg

Height above the floor  = 1.5m

g  = 9.8n/kg

Unknown:

Potential energy  = ?

Solution:

The potential energy of a body is the energy due to the position of the body.

It is mathematically expressed as:

  Potential energy = mass x acceleration due to gravity x height

  Potential energy  = 4 x 9.8 x 1.5  = 58.8J

Answer:

35kg
