Answer:
Mass of the object, m = 24.14 kg
Explanation:
It is given that,
Height above the ground, h = 2.4 m
Gravitational potential energy, PE = 568 J
We need to find the mass of the marble. The definition of gravitational potential energy is given by the product of mass, height and acceleration due to gravity. i.e.
PE = mgh
[tex]m=\dfrac{PE}{gh}[/tex]
[tex]m=\dfrac{568\ J}{9.8\ m/s^2\times 2.4\ m}[/tex]
m = 24.14 kg
So, the mass of the object is 24.14 kg.
