Question

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​

Answer 1

58.8J

Step-by-step 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
