Answer:

19.6 J

Explanation:

The following data were obtained from the question:

Mass (m) of object = 2 Kg

Height (h) = 1 m

Workdone =?

NOTE: Acceleration due to gravity (g) = 9.8 m/s²

Thus, we can obtain the workdone in lifting the object by using the following formula:

Workdone = mgh

Workdone = 2 × 9.8 × 1

Workdone = 19.6 J

Therefore, the workdone in lifting the object to height of 1 m is 19.6 J
