Answer:
19.6 J
Step-by-step 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
