A box of books weighing 15.5 Newton is lifted 12 meter how much work is done

Answer 1

Work = Force (in the direction of motion) x Distance

So. the force is 15.5 N (it's the same as the weight in this case) and the distance is 12 meters.

Work = 15.5 N * 12 m = 186 N-m or 186 J (J stands for joules).

Enjoy!
