Answer;
= 58.8 joules
Solution and explanation;
Potential energy is given by the formula;
P.E = mgh where;
m is the mass in Kilograms
g is the gravitational acceleration (m/s²)
h is the height/distance in meters .
-Well the ball is held from the ground of a distance 1.5 meters, so, h = 1.5 m.
The mass of the ball is 4.0 kg, so m = 4.0 kg
Hence;
P.E = (4.0 kg) × (9.8 m/s²) × (1.5 m)
= 58.8 Joules
