Answer:

77.91 J

Step-by-step explanation:

From the question given above, the following data were obtained:

Mass of object (m) = 5.3 kg

Height (h) = 1.5 m

Workdone =?

The Workdone can be obtained by using the following formula:

Workdone = mgh

Where the acceleration due to gravity (g) = 9.8 m/s²

Workdone = 5.3 × 9.8 × 1.5

Workdone = 77.91 J

Therefore, the Workdone in lifting the stone to a shelf that is 1.5 m is 77.91 J
