Question

a pair of bullocks exerts a force of 140 Newton on a plough. the field being ploughed is 15 m .long how much work is done in ploughing the length of the field​

Answer 1

HERE IS YOUR ANSWER :


GIVEN:


Force = 140N

Displacement = 15m

NOW, As we know ,

Workdone (W) = Force(F) × Displacement(s)


=> 140 × 15

=> 2100 J


So, Workdone = 2100 J


HOPE IT HELPS U..

Answer 2

f=140N

s=15m

∴w=f*s

140N*15m

2100J
