Answer:
100 Joules
Step-by-step explanation:
The question is testing on how to calculate work done;
We are given;
- Mass of an object is 5 kg
- Distance moved is 2 m
We are required to calculate the amount of work done.
How do we calculate work done?
- Work done is the product of force and distance.
- Therefore without distance covered no work is done.
- Work done = Force × distance
- Additionally, it is measured in joules or Nm
In this case;
Force = mass × 10 N/kg
= 5 kg × 10 N/kg
= 50 N
Therefore;
work done = 50 N × 2 m
= 100 Joules
Thus, the work done in lifting the object is 100 Joules
