A pair of bullocks exerts a force of 140 N on a plough. The field being ploughed is 15 m long. How much work is done in ploughing the length of the field?
Question
A pair of bullocks exerts a force of 140 N on a plough. The field being ploughed is 15 m long. How much work is done in ploughing the length of the field?
Solution
To calculate the work done in ploughing the length of the field, we can use the formula:
Work = Force × Distance
Given that the force exerted by the pair of bullocks is 140 N and the length of the field is 15 m, we can substitute these values into the formula:
Work = 140 N × 15 m
Now, we can calculate the work:
Work = 2100 N·m
Therefore, the work done in ploughing the length of the field is 2100 N·m.
