Respuesta :
m = Mass of the bowling ball suspended above the surface of earth = 6 kg
g = Acceleration due to gravity by earth on the bowling ball = 9.8 m/s²
h = Height above the surface of earth = 3 m
U = Potential energy of the bowling ball
Gravitational potential energy of the bowling ball is given as . hence
U = m g h
inserting the values
U = (6) (9.8) (3)
U = 176.4 J
Answer: 176.58 J
Explanation:
A body possess potential energy due to virtue of its position. It is given by:
P.E. = m g h
where, m is mass of the body, g is acceleration due to gravity and h is the height at which object is placed.
Given:
m = 6 kg
g = 9.81 m/s²
h = 3 m
⇒P.E. = 6 kg × 9.81 m/s² × 3 m = 176.58 J
Hence, the potential energy of a bowling ball having mass 6 kg and suspended at a height of 3 m is 176.58 J.
