Answer:

The answer to your question is height = 9.20 m

Explanation:

Data

Work = 587 kJ

mass of the body = 6500 kg

height = ?

Mechanic work is defined as the force applied to a body times its mass.

Process

1.- Calculate the weight of the body

weight = mass x gravity (9.81)

weight = 6500 x 9.81

            = 63765 N

2.- Calculate the height

height = work / weight

-Substitution

height = 587 000 / 63765

-Result

height = 9.20 m
