Answer:
59,566.32Joules
Explanation:
The question is incomplete. Here is the complete question.
At a construction site, a crane lifts a steel beam with a mass of 330 kg.
i. What is the gravitational potential energy added to the steel beam when the beam reaches a height of 18.4 m? (1 point)
Gravitational potential energy GPE = mgh
m is the mass of the steel beam = 330kg
g is the acceleration due to gravity = 9.81m/s²
h is the height the beam reaches = 18.4m
Substitute
GPE = 330 * 9.81 * 18.4
GPE = 3237.3 * 18.4
GPE = 59,566.32Joules
Hence the gravitational potential energy is 59,566.32Joules
