In order to increase the gravitational forces between two objects,
you have exactly two choices:
-- Increase the product of the two masses.
-- Decrease the distance between their centers of mass.
Answer:
The mass of the ball is 1.360 kilograms.
Explanation:
By Work-Energy Theorem, gravitational potential energy (
), in joules, is the product of weight of the ball (
), in newtons, and height (
), in meters. Please notice that weight is the product of the mass of the ball (
) and gravitational acceleration (
), in meters per square second. Then, the formula for the mass of the ball is:
(1)
If we know that
,
and
, then the mass of the ball is:


The mass of the ball is 1.360 kilograms.
