Answer:
2.27kg
Explanation:
The Potential energy gained = Force gravity× Height
Force gravity on the ball is GPE/ height
56.8/2.5=22.72N
the mass = 22.72/10= 2.27kg
The mass of the ball when the gravitational potential energy of 56.8 J present is 2.27 kg.
The potential energy is the energy by virtue of its position in the effect of gravity.
Given is an exercise ball is on a table 2.5 m above the ground. It has a gravitational potential energy of 56.8 J.
Potential energy = gravity force × height
P.E =mgh
56.8 J = m x 9.8 x 2.5
m = 2.27kg
Thus, mass of the ball is 2.27 kg.
