Answer :
Final answer:
The work done when lifting an object can be calculated using the formula: Work = force x distance. In this case, the work done is equal to 735 J.
Explanation:
To calculate the work done when lifting an object, you can use the formula:
Work = force x distance
In this case, the force is equal to the weight of the object, which can be calculated using the formula:
Force = mass x acceleration due to gravity
So, the work done is:
Work = (mass x acceleration due to gravity) x distance
Work = (25 kg x 9.8 m/s^2) x 3 m
Work = 735 J
Therefore, the correct answer is option a) 735 J.
